-S (-ES)
When I use words "nobody" "somebody" "everybody" must I use -s(-es) after a verb?

Nobody know - Nobody knows

I know, that I must use -s in this situation, but I have watched an English cartoon, where I've heard "nobody know" and I was wondered.

Answer

You are right. The words "nobody" "somebody" "everybody" are singular nouns, so they need to take the same part of the verb as he, she and it.

Nobody knows
Nobody is
Nobody has

'Nobody know' is incorrect.

Answer

what cartoon was that?
