He is absolutely hilarious. The set I'm referring to is the one where he is talking about Stephen Hawking. It is in a comedy room somewhere. There is another one in French and is a TV special. Both are funny as hell. Just about everything he had on there has been purged from YouTube but you might find them on one of the alt tubes. When he's in character he's really good. I came across his channel back in the day when it was literally called The NASA Channel. Needless to say, they got rid of that one in a hurry and all of his good videos have mostly been purged. Shame, that shit is comedy gold.
