A guy walks into a post office one day to see a middle-aged, balding man standing at the counter systematically pasting "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. The guy's curiosity gets the better of him and he walks up to the balding man and asks him what he is doing.
The man says, "I'm sending out one thousand Valentine cards signed, 'Guess who?'"
"But why?" asks the guy.
The man replies, "I'm a divorce lawyer."
