Fish Movies
Let your stories tell themselves.
Never say "you should have seen the size of the one that got away" when you can say "hey, take a look at the size of the one that got away." A new camera based on the colonoscopy pill camera could make this happen. The camera would be disguised as a weight (or lure if you want to see the innards), and start filming the minute the fish struck and you hit the record button. If the fish got away you could then play back the tape to show all of your friends you weren't lying. A bonus feature would be a weight calculator that could figure out how much the fish weighed based on the dead weight during times when you were pulling it in and it wasn't fighting back.
