Joke of the Day (Thanksgiving Day)

It's all in the punctuation:
An English professor wrote the words, "Woman without her man is nothing" on the blackboard and directed his students to punctuate it correctly.
The men wrote: "Woman, without her man, is nothing."
The women wrote: "Woman: Without her, man is nothing."

Man + Woman = ???
Smart man + Smart Woman = Romance
Smart Man + Dumb Woman = Pregnancy
Dumb Man + Smart Woman = Affair
Dumb Man + Dumb Woman = Marriage
