There is a goldmine of Andy Kaufman footage on YouTube right now, and I'd like to link to a couple of my favorites in the next few days.
First up, a really weird clip - supposedly 16mm film footage of the actual assassination of President Lincoln. In his early days as a performance artist, Andy would play this for stunned audiences - who would often be moved to tears at its content.
Of course, it's a hoax. But Andy would often lead the audience in silent prayer afterward anyway just to screw with them.
Update: The footage is actually from D.W. Griffith's film Birth of a Nation (1915).
