When I was about ten or eleven years old, my Dad woke up from his afternoon nap and went down to the dock and climbed into his fishing boat for some late afternoon fishing. When he cranked up the outboard motor and put in gear, it jumped off the transom and sunk to the bottom. He'd unclamped it from the transom for some unkown reason. It's still funny to this day, but I didn't laugh then. No-siree! I got nominated to dive down and hook a rope to the motor so Dad could pull it up.
