An old joke, but still going strong:
Ben walks into a post office one day and sees 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.
Ben’s curiosity gets the better of him; he goes up to the balding man and asks him what he is doing. The man says, “I’m sending out 1,000 Valentine cards signed, ‘Guess who?'”
“But why?” asks Ben.
“I’m a divorce lawyer,” the man replies.

I like lawyer jokes. So sue me. No, on second thought, don’t sue me.
