It's a voyeuristic sort of thing. To see just how far some people will go for money. Some folk never cease to amaze me how far greed will take them. There's an australian show similar to this that I watch sometimes too. Can't remember the name, right now.
For what it's worth, I don't go out of my way to watch it. I'll watch it if I see it while flicking.
Some dude ate a hissing cockroach for $75. For an additional $200, he ate a second one.
That's about as bad as the girl who shaved her head, had her hair mixed with butter, then ate the hair/butter mixture and washed it down with heavy creamer. :throwup:
