Best digital short is Taco Town. I was in tears when that first aired. It just kept getting more and more ridiculous!
There is a skit I saw in a rerun on Comedy Central when I was in my dorm (Beyer Hall). It was from the mid-80's era when Billy Crystal and Martin Short et al were on. They were playing WWII soldiers storming a house and they had to get upstairs. Billy Crystal orders Martin Short to get to the second floor but soon realizes he can't climb stairs after several efforts in vain because, as Short states, "it never came up" in his life. Just try to visualize Martin Short attempting to climb stairs and failing miserably.
Has anyone else seen this skit? I have never seen it since that day, but it may be the funniest thing I've seen on SNL.
