Once there lived twin brothers named Jack and Jim. Jack was married and Jim was single, but the proud owner of a dilapidated old boat.  Disaster struck them both on the same day: Jack's wife died and Jim's boat sank. A few days later Jim met a friend on the street who mistook him for Jack and offered his sympathies saying:

"You must feel really terrible."

"Oh, not really," said Jim, "she was an old wreck from the beginning. Her bottom was all shriveled up and she smelled like dead fish.  The first time I got into her, she made water faster than anything I have ever seen. There was a bad crack in her back and a pretty big hole in the front. The hole got bigger each time I used her and she leaked like crazy.  But what finished her was these five guys I know borrowed her. I told them she was no good, but they said they would take a chance with her anyhow. So I rented her out, then these crazy fools all tried to get into her at once, and it was to much for her. She cracked right up the middle..."

The friend fainted.
