The Katherine is a Master of Science!

[snowgrett14]

Gosh I love this music :)

[thewolffromhell66666]

hank you lucky bastard

[EmsterDoctorWho11]

they talk the same...its adorable!

[roxypathfinder]

I want to grow up to be just like Katherine. She is my rolemodel

[GKTiffanyMariah]

She did get a dog... a hot dog. 

[bayace92]

I don't know what he knows what he knows. I think.

[DarthRaye]

Ahh! Next challenge: John vs Hank in a Sumo Fight B]

[Caolaidhe13]

I love how The Katherine is dancing and the guy next to her is totally stoic. :)

[Radioplaya]

I really love this video

[nekoninja1234]

The Katherine is among the the most adorable human beings alive. Her dancing at 1;41 is awesome.

[HolmeDawg]

Well, they did get SOME kind of a dog... :D

[KrypticSalamander]

2:05 random ass-slap

[moviemoviemadness]

@KrypticSalamander nah not random in baseball (and most other sports) an ass slap is considered a way of saying good job

[FantasticBrina]

I want to grow up to be exactly like the Katherine :)

[SerpentsNightmare]

Do you guys think The Katherine will ever write a short story titled "An Abundance of Johns?" I think she should.

[BalletBeauty97]

@awsomeman113 I have yet to find any suitable Nerdfighter guys in my town... Forever alone.

[mypatronusisaDalek]

BINDER HAND

[FlargTheKitty]

Katherine is exactly the type of funny that I love.

[3BsAlaska]

i have been watching Hank and John for about a year now. and i have never seen Katherine before. i always heard her voice in Super Mario Bros Wii and Legend Of Zelda Skyword Sword, but have never seen what she looks like. Shes gorgeous!!! and funny!! i love her!! <3

[GrapefruitFactor]

I've watched this video at the very least thirty times. I do not know why. But I love it! <3

[LilaRose89]

Katherine, have my lady babies. You are so made of awesome.

[Quintinia]

Katherine is the second most adorable Green family member, after Henry.

[iammehowru]

"We didn't get a dog"

And a few months later there was Lemon.

[thefrozencombustion]

Got to say not a huge fan of Kathrine. She seems childish and immature.

[Throrindor]

@thefrozencombustion I think she only acts that way when she's in the comfortable company of friends and close family. I'm sure that when a situation requiring adult/professional composure arises, she is perfectly capable of taking on a more mature disposition.

[luisitagil]

to me THE KATHERINE is the QUEEN of youtube!!!!

[LindseysBackyardLive]

At Montana ball games they have sumo wrestlers. In Pittsburgh, we have perogies.

[ohhisabellaa]

"I'm a master of sciencee motherfuckeerrs. get outta my wayyy bitchess."

[yourworstnightmar231]

i loooooove the katherine soooooo much! Katherine you're my idol!

[mariahrose210]

I really hope that is Hank in the sumo suit

[unscrewstheotherway]

This is adorable jsdhkagjhkfjhl

[francophileMUC]

:D

Hank and the Katherine are sooo cute.

[Musiclover1494]

Can you adopt me?

[mybestfrendsafrog]

=O You said "baby" at the end! I think you meant Adult Female =)

[MissMeggie2804]

That's so cute! I love you guys

[chanym1992]

Hank I see why you love Katharine she looks really awesome.

[smileyskippy13]

they're so cute!:)

[Lol90796]

I love the fact the incredibly smart Master of Science has invented BINDER HAND :D

[starkidfangirl]

She is the most perfect person for Hank in the entier universe and all its parallels :)

[123456789robbie]

@starkidfangirl well, what about the paralel where she needs glasses, and therefor has the added adorableness of wearing glasses?

[JAMBO4358]

I'm not one for finding fault... but surely Strange Charm would be a more applicable song?

[VolunteerNerdfighter]

@JAMBO4358 The song about quarks?

That was written in the future, as far as this video is concerned. ;)

[TheGaselli37]

HANK!! YOU AND KATHERINE ARE AWESOMELY ADORABLE TOGETHER!!

[OllieKickFlip378]

The Katherine reminds me of Meekakitty :-)

[hellogoodbye201409]

Awww The Katherine is so cute! :DD

[4LiveLifeWithLove4]

From 0:37 to 1:01 is super funny! And so is the whole thing! The Katherine is so amazing! And he and Hank are so cute together! I want to find my Hank someday! So many exclaimation points!!!

[Kamades1]

So I just realized that The Katherine got her Masters of Science on my BIRTHDAY! HORRAY! SHARED DATE THINGS! DFTBA

[IlnousaimeleMonsieur]

In which Hank harmonizes to Take Me Out to the Ballgame. :P

[thesuperchony13]

will you adopt me? ;3

[harrySTINKINpotter]

Aww shes so pretty!

[PteradactylKat]

I adore The Katherine's eyeglasses.

[musicluv922]

aw, your the perfect couple. Katherine is so pretty!

[Squishytrishy]

What a very sweet video :)

[AlliciaZora]

This is quite possibly THE cutest thing I've seen all year!

[IslamChika]

This is the cutest thing I've ever seen....

[powergannon]

YAY the 10 word song returns

[thenarcolepsist]

True love

[spaztaastic]

Oh, and she can harmonize very nicely :)

[spaztaastic]

Your wife is amazing!!!!!!!!!!!!!!!!!!!!!1

[mirosango14]

she's a master of science now? there's only one thing she can do; think about things. think about things a LOT.

[Qwerkss19]

One of the greatest ways you can tell how much Hank truly adores The Katherine is by how he films her. He just wants to chronicle the adorable.

[TheJacksonification]

I love the guy sat a couple seat across from Katherine when shes dancing at the Baseball... trying his best to ignore her :)

[dolphin64575]

@TheJacksonification he was STUDIOUSLY ignoring her happy dance

[willderphil]

Its nice to see katherine. I am used to listening to her now from Hanky Potter but its nice to put a face to the voice.

[coconutnacho]

well isn't that just lovely :)

[TheAglover26]

65 people are not a master of science.

[SHALYN8]

This is seriously my all time favorite Hank song. I catch myself singing it when I'm alone and/or thinking about something I know.

[dulcepekpek]

I understand Hank so much better now.

[Irimar14]

That's a very fun wife you have there. As the below comment say. You guys are made for each other!

[BalletBeauty97]

Oh my gosh... The Katherine and Hank are like.... made for eachother!!!! Gah! -3

I wanna find my Hank, one day...

[FredIsMyName22]

@BalletBeauty97 I'm right here.

[YoshiLebrax]

@FredIsMyName22 But your name is Fred! D:

[FredIsMyName22]

@YoshiLebrax Names can be changed.

[xaveir14]

@BalletBeauty97 I need to find me a Katherine

I'm sorry to say that you're going to have a harder time than me

Because as we all know

There is an Abundance of Katherines

Hopefully there is a plethora of Hanks as well

[awsomeman113]

@BalletBeauty97 Where are all the nerdfighter girls in my town like this one?

[littlemegamonkey]

@BalletBeauty97 i agree. i want to find my Katherine one day.

[MarchingMachine]

Who would dislike this? Really? This is a funny song and a guy who CLEARLY loves his wife and her accomplishments. Are you *that* negative. I realize its hella late, but Congrats to Katherine.

[Plumbobrockstar]

This music cracks me up :P

[aplethoraodirigibles]

This is the first time I have ever seen The Katherine.

[violaplayerforever]

Oh the Katherine, you are amazing on so many levels.

[bushybrennan]

[AffiliatesOfAwesome]

The Katherine is so pretty. O.O

[xSobhan]

1:51 she looks like the key of awesome guy :p

[strickerman101]

Or his hank a replica of Katharine? The world may never know!

[hotshot3434]

this didnt have much science in it......

[niminonono]

To all the comments...

I think Hank is an exact replica of Katherine

[Ayshafr]

The Katherine is awesome.

[iAmErica1234]

The Katherine is practically an exact replica of Hank. It's adorable to watch you two together.

[Tsugo582]

baseball games look like fun.

[holycrapitsalex2112]

BALLLLLL GAAAAAAAME

xD

[FrizbeeChique77]

[chaudree]

@FrizbeeChique77 AHHHH, headdesk ;D

[Last42Tides]

The Katherine is a lucky woman!

[jongmagee]

[vicky216n]

Aahhh she's awesome!

[everlongview7]

The end makes me smile =)

[everlongview7]

The end makes me smile =)

[iloveduckyboi]

Katherine looks a LOT like my boyfriend's sister Kate.

[TheWarnerSister]

The Katherine is adorable. :D

[oneorangespider]

I like how about an hour after Katherine became a master of science she also became a master of the BINDER HAND.

[silverturtle14]

"BINDER HAND!!!!"

[violinchick89]

The Katherine is adorable!

Could she be in more videos? :D

[gymnast4301]

i'm gonna say it. french the llama you guys are awesome!

[hannahw2071]

@gymnast4301 Hahahahahahahahahahahaha! French the Llama your comment is awesome! 

[TheRealNotSteve]

Who was dancing in the music when it played? Just me?

[harrypotterplz89]

You two are nerdfighter soul mates.

[starzus]

Vlogsister in law, congratulations on your Katherineness

[NerdfighterCutty123]

Adorable Katherine is adorable :)

[ljkolnick]

Aaaadorable! I can see how you guys are perfect for each other!

[wishxxfulthinker]

So upon reading the title of this video I thought the Katharine was going to do a science experiment or something! I was so confused until I read the dooblydoo! Congrats the Katharine!

[xPwnyTailx]

I Love the Katherine.

[getalife768]

I love where she's dancing at the ball game and in the background there's a guy sitting there, completely straight-faced.

[ferngirltlc]

I feel motivated to buy your "I know" song. But I'm afraid that if I do, I'll have to buy all of them...

[PennyLane0123]

in the info box, i thought it said 'hanks wif*i* gets her degree.' i was a little confused til i read it again. but awesome video!

[AllieYourAlly]

The Katherine and the Yeti seem to have similar voices....

And they also have the same-ish speaking patterns as Hank & John...

That's probably what happens when people spend lots of time together...

[cuuuuuuuuuute!!]

[raggamuffins13]

I love how people who don't wear makeup are so much more beautiful than people who do.

[Jessmo198]

haha lucky woman xD

[SamTalmadge]

SOULMATES!

[NotPanicking]

I've never paid any close attention to baseball, but I would just like to point out my incredulity when I saw that that pitcher's LEG went over his HEAD. T'ain't natural.

[newpepsipopup]

I don't think your wife is a person. She's a combination of your DNA, and someone else's too (but that person has to be awesome).

That means she is ACTUALLY made of awesome.

[Katfuzzmunchkin]

My name is Katherine C:

[grandchildofchaos]

@Katfuzzmunchkin And my name is Sarah

[tya8413]

Wow 2 great things Katherine and the 10 word song, both pretty awesome.

[inforthelose]

Good thing you got this Katharine. I hear there's an abundance of them.

[OllieKickFlip378]

@inforthelose I have that book!

[emsGotAProblem]

@OllieKickFlip378 yeah. John wrote it

[roofboy179]

Hank's Katherine is my favorite Katherine.

[Thoroughbred17]

Good God, your wife is awesome.

[byScrooby]

"God: Hidden Science" - Google it!

[InsaneMentalist]

Grats Wife-of-guy-I've-started-to-fo­llow-blog-of. You are now a scientist, and if Sphere is any indication, female scientists survive as long as they don't get really stupid halfway through and devoured by impossible squid creatures from a alien sphere of intelligently awesome metaphor.

[pete275]

SCIENCE

[xXmusicxjuniexX]

why cant we see the Yeti? we just saw the Katherine and her cuteness didnt break my computer....

[TrickstersBrain]

CONGRATULATIONS KATHERINE!

Sorry I'm a bit late there.

[ThomasStillbranch]

Kathrine has a mouth on her XD

[katiexcoree]

Hank capitalizes words like Margo does.

[regularguy5mb]

OMG!! Congratulations O Katherine of the mighty binder hand!!

[panicatthediscoROCKZ]

binder hand!!!

[nicciweasley]

That is great! Congrats Katherine!!!!!!!!

[MarlonOwnsYourCake]

23!!!!

[myxgiftxisxmyxsong]

@pem440 It's called I Know (A Song in Ten Words). =)

[fr0gl3ss]

omgosh that bit at the end was sooooo sweet **tear**

[NoirRock]

The Katherine is SO cute.

[crazylanea]

I love Montana even more now, seeing that Osprey nest platform right by the baseball diamond.

[briannafucker666]

congratulations, katherine. what does being master of science mean, now? I=Not-Science-Smart...At-All.

[splicegrrl]

congrats, katherine!! :)

[ljlightfire1]

she does talk like hank :o

[BellsWolf]

Oh. My. Gosh. Your wife sounds/talks exactly like you. 0.o

[MsFunnyFace]

Dear goodness gravey. I love Katherine. Will you adopt me? I mean, I'm twenty years old... but still...

[372monkey]

@MsFunnyFace ooooo me too!!!!!

[magicaltrevrox]

zohmygod your wife is awesome!

[mixtapebang]

The Katherine is the cutest thing ever! Shes so funny.

[lickmelacroix]

Congrats Katherine!

I'm sure you actually know how to spell that and don't have to avoid it by spelling 'congrats' every time instead! Haha

[KristaAshleigh]

ahh so this is " the katherine" she seems very excited!

[DragonFire381]

You got her such a pretty ring, Hank!

[wangpronouncedwong]

Haha, that was fantastic. Congrats!

[koratheexplora]

Not only is Katherine a Master of Science she is a Master of Dance! Congrats Katherine!

[mondaypatrol]

Congrats Katherine! You are indeed the Master of Science!

[avidhpfan]

Congratulations, Katherine!

[Helgacabbage]

Congratulations, Katherine!

Don't Forget That Brains Attract! DFTBA

[namlhots]

This news is almost as good as son Joe getting his Bachelors. Congratulations Master of Science.

[awsomenaruto94]

i didnt know your wife's name is Katherine but i find it odd since ummm u wrote a book about girls named Katherine

[Helgacabbage]

Actually it was Hank's brother, John Green wrote the book 'An Abundance of Katherines'.

[Nanosauromo]

No he didn't.

[DragonFire381]

Yeah he did. It's kinda right there.

[Nanosauromo]

My comment was in response to awsomenaruto94's comment, not Helgacabbage's.

[DragonFire381]

Oops, I'm sorry!

[pem440]

come on nerdfighters don't mark his comment as bad. he is just misinformed.

[singerdancer8891]

i love how she added harmony in "old ball game."

...i do that...

[rebeccaontheearth]

Congrats! :)

[CallidoraLBlack]

Congratulations, Katherine!

:o)
