His naivety makes Ricky Gervais laugh hysterically, so Gervais arranged for a world travel show for the purpose of making Karl befuddled, frightened, and upset.
I like the Ricky Gervais Show, yet didn't have high hopes for this. The funniest parts aren't Karl, but the others making fun of him. But this is pretty good.
A lot of people seem to think he must be an Ali G kind of character, but if you observe him for a while he is never not 100% sincere. That's why he's adorable.
I can't figure it out. There's not a comedian or a genuine fool out there who can be so consistently funny. I have just as hard a time believing the one as the other.
