Recently a "Barak Obama" impersonator was hired by some Republicans for a recent gathering. Apparently his jokes hit a little to close to home when he turned attention to some high ranking Republicans. Some of his jokes got a bit of a delayed reaction. In particular when he started taking shots at the Tea Party. Eventually his microphone was cut off and he was removed from stage.
My question is, what did you expect? He is an insult comic. Anyway, you can see his little performance below should you desire.
