haha i wouldnt be suprised. My favorite episode i saw when i was in London on vacation and at the end they put all of the money he could win inside toasters and turned them on. The contestant had to answer all of the questions before his money burst into flames, he actually saved most of it but it was funny as hell.
and on one they put cacti around the buzzers and then ask really simple questions (i.e. What color is the sky) and all of them would try to go really fast and get a handful of thorns. great show.
