“The only real laughter comes from despair.”

“From the moment I picked up your book until I put it down, I was convulsed with laughter. Some day I intend reading it.”

“Come on in girls, and leave all hope behind.”

“Love flies out the door when money comes innuendo.”

“I could dance with you till the cows come home. Better still, I'll dance with the cows and you come home."Groucho Marx was never one to pass up an opportunity for a play on words and this occurs in his dialogue of the 1933 film Duck Soup:”

“A man is only as old as the woman he feels.”

“Only one man in a thousand is a leader of men -- the other 999 follow women.”
