Remeber that episode of the Simpsons, 'Twenty Minutes Over Tokyo', when the family had to take part in a crazy Japanese gameshow? This programme is pretty similar, in that the contestants have to undertake a series of physical challenges, that usually end with them getting hurt, or soaked with water.
In the UK, Challenge TV shows this at around 6:00pm most days of the week. Not sure about elsewhere though.
I recommend that you see it at least once, just for the novelty value. It's pure slapstick, packed with giant plastic sets, and men in rainbow-coloured outfits. Even Craig Charles' abysmal voice-over can't ruin it.
EDIT: Don't know why I posted this in World Events. Idiot.
