A guy walks into a post office one day to see a middle-aged, balding man standing at the counter methodically placing "Love" stamps on bright pink envelopes with hearts all over them. He then takes out a perfume bottle and starts spraying scent all over them. His curiosity gets the better of him and he goes up to the balding man and asks him what he's doing.
"I'm sending out 1,000 Valentine's Day cards signed, 'Guess who?'"

"But why?" asks the man.

"I'm a divorce lawyer."
