I just saw this (faked) Talk-Show recently and it was the most funny thing i have seen in a long time. Sure there are just 8 episodes by the time i am making this review but you definitely have my recommendation. It is one of the few shows you like to turn off while watching because Mr. Galifianakis is hilariously awkward and embarrassing in a way that makes the viewer feel uncomfortable as well and i love that!
Most of the guests are doing a great job just being confronted with these questions and they react in a way that you have never seen in any of their actual movies. For example have you ever seen Ben Stiller being mad and/or angry in a way that you do not want to laugh at that? No? Then go and check it out!
You can find most of the 3 - 5 min. clips on Youtube so go and check it out!
