An English professor wrote these words

 

"A woman without her man is nothing"

 

on the chalkboard 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."

 

 

 

 

 Punctuation is everything
