Man, I was so going to grammar nazi this thing, but decided it would ruin the joke. But, y'know, since you started it..

All of the people in the class fail. The statement 'a woman without her man is nothing' is already grammatically corect and needs only a period at the end by way of punctuation. The students are all adding unnecessary punctuation and obfuscating the meaning of what would otherwise be a simple statement. The prof gave the class a trick question and they fell for it.

Had the statement been 'without her man a woman is nothing' then punctuation would've been necessary, but that's not corruptible by the women and is therefore unsuitable for the purposes of this joke.

Also, I think responding to a sentence fragment with another sentence fragment in order to point out the first sentence fragment is hilarious. I'm a nerd like that.
