"An English professor wrote the words, "a woman without her man is nothing" on the blackboard and directed the students to punctuate it correctly.
The men wrote: "A woman, without her man, is nothing."
The women wrote: "A woman: without her, man is nothing." "
There's also this gem of a page that's been floating around on Facebook:
'Let's eat Grandma!' or, 'Let's eat, Grandma!'
Punctuation saves lives.
