Just started watching An Idiot Abroad, it's so stupid it's funny. I haven't decided if I like it or hate it yet but will continue on to episode three tonight.
In season 2, they make him do stupid things like bungee jumping, and diving with sharks in a cage.
Karl says one of my favourite lines in any TV show ever when he's in the water with a Great White.
"It's like when you're driving and there's a wasp in the car, you just can't relax".

They've done a 3rd season, but it's starting to get a little boring. Season 1 was the best.

It's funnier than Idiot Abroad (IMO).
