Allow me to do some early lobbying on Adam's suggestion for a best SNL skit contest.
Colonel Angus wins hands down. It has always been my favorite. I have watched it dozens of times, and it never gets old.
I count almost 40 jokes in the 5 minute skit, including a couple lines by Christopher Walken that the audience seemed to have missed, like "Taint really sure" and "Who is this little rosebud?"
