Walking into the post office, Jack saw a middle-aged, balding man standing at the counter busily placing 'love' stamps on bright pink envelopes with hearts all over them. The man then removed a perfume bottle from his pocket and started spraying the scent on the envelopes.

Jack was overcome with curiosity and asked the man what he was doing.

"I'm sending out 1000 Valentine cards signed 'Guess Who'," the man explained.

"Why?" asked Jack.

"I'm a divorce lawyer," the man replied.
