The best part is watching Seinfeld's 'I just said the punchline' face at 1:27. At this speed, you can see that for a split-second he's has the defiant grimace of Conan the Barbarian overthrowing a mad king.
Simple trick!? That's two million years of harnessing technology and conquering nature to make Seinfeld funny. It took no less than the combined efforts of the whole human species and it didn't even really work.
