The Power of Punctuation

An English professor wrote the words:

"A woman without her man is nothing"

on the blackboard and asked his students to punctuate it correctly.

All of the males in the class wrote:

"A woman, without her man, is nothing." 

All the females in the class wrote:

"A woman: without her, man is nothing."

Did you realise what difference can a punctuation mark make to a sentence.
