Just been reading the forums and someone found a show in Tailand I think called Pinoy Henyo. It has what is a yes/no game with someone who sits in a gunge tank and gets gunged.
So when will they bring this show to the uk :)
If you want to have a look search youtube for "pinoy henyo"
Here is a link to some image of a slightly messy pictures set
