Anything done by Monty Python.
Thread won. That has got to be one of the best comedy sketches in history.Also I always giggle when I picture the image of a fat old man in a diaper dancing around a sprinkler. The only time I saw it done was on the Sprockets sketch on SNL.
Tourettes guy. Yes its stupid. Yes its immature and yes, its probably fake. But it made me laugh more than anything else ive evere seen. Just type in tourettes guy (or however you spell tourettes) on you tube.
