You know that reality show on cable called "Deadliest Catch", where they follow crab boats around the North Pacific? Kinda boring, right?
Well, I was thinking that into every promo they should insert a staged scene of a crewman with a large crab attached parasitically to his face. He'd be writhing on the deck and screaming, "get it off, get it off" while a big guy with an ax prepares to perform a mercy killing on the poor schlub. Then the next scene would just be some mundane shot of crab pots being rigged or something.
The parasite crab would not appear in any actual episode, but would generate huge ratings nonetheless.
