Sayonara Zetsubou Sensei OP

is this like a particular opening cause when I watch the episodes I haven't seen this opening yet.. but the first episode I ever saw was on Crunchy Roll, the one where we learn about the girl who can't speak except through her cell phone? and that had this opening. but as of episode 3 that I'm watching its not using that opening.. whats up?

the show is just so funny i love it.

This anime is a definite thumbs up. I would recommend it to anyone.
The humor was actually funny, unlike most unfunny animes where they try to make you laugh by showing a character eating a lot or by a female character calling everyone 'baka'. Seriously, those types of anime are just plain stupid, moronic and idiotic.
I don't know how people laugh at them. Worse, I don't know how people actually QUOTE them...
Those people need to be sent to mars or something...

any suggestions for shows like this one? also are there anything else after the second season?

there is a third season to this one but as for suggestions for shows I wouldn't know any.

Yes, second season is called "Zoku Sayonara Zetsubou Sensei"

this series is just total mind screw. the intro is misleading, there is no plot, and the most things that happen aree just random. I abosutly love it^^

Guess who started watching this show thinking it would be a fairly serious anime that would have almost no laughing moments?

Guess who was wrong?

who sing ?

Kenji Otsuki along with the voice actress of some of the girls of the show.
