This comment won in so many ways.

[Joel Nepomuceno]

I just asked about the pronunciation, not the meaning. Anyway, thank you... I guess...

[Conor Mohan]

This made my brain fucking implode even more than that season 7 finale of Doctor Who.

[therealmusiclover69]

there is no difference in pronunciation. English does that a lot.

[RhyzaHsX]

Both Pronounced the same :)

[Imwudyn]

They're pronounced the same weigh. =3

[Recce17th]

That guy went full retard, you never go full retard.



[HellsWolff]

The pronunciation is the same.

[Piers Ackroyd]

You said that the speed of push was the speed of sound, and then displayed it as "761 mph". But isn't that the speed of air through air? Isn't the speed of push, the speed of sound through the object that's being pushed?

[Xmetalearth]

Every time I weigh myself now if I see increase in weight I'm gonna blame it on the light.
