[And this better not turn up as an Endemol production any time soon – I’m retaining copyright on the idea for the good of humanity] How Low Can You Go?
Two teams of contestants compete for cash prizes. Each round one person from each team is picked to perform a terrible stunt (eg. worm eating), and is offered an amount of money – say a thousand pounds. The contestants then underbid each other to see who’ll go the lowest, and how low they’ll go to do the stunt which they then have to perform to win the cash.
Simple mechanic. And the worst kind of TV.
