A woman 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 woman’s curiosity gets the better of her and she walks up to the balding man and asks him what he is doing.

The man says: “I’m sending out one thousand Valentine’s Day cards signed, ‘Guess who?'”

“But why?” asks the woman. The man replies: “I’m a divorce lawyer.”
