Dude I don't know about you other guys but I've been watching "Da Ali G Show" recently and man, this show is absolutely hillarious. Basically this actor has three different characters that he portrays and he does real-life interviews with unsuspecting very serious people.
He basically acts out the 3 personalities as though they are very ignorant and the people have to deal with his ignorance.
There have been 2 seasons so far and he might not be able to do a 3rd season because people are starting to learn about who he is and I'm sure it makes it harder for him to get interviews with important people.

Yo, I'z out. Respek!
