A woman walks into a post office to mail a letter. She notices a man standing at the counter with a pile of pink envelopes. She watches as he places a Love stamp on each one and then sprays it with perfume. 

Her curiosity gets the better of her, so she approaches the man. "What are you doing?" she asks. 

"I'm mailing 1,000 Valentine's Day cards signed, "Guess who?"

"Why would you do that?" asks the woman. 

"I'm a divorce lawyer," was the man's reply.
