On this weekend's episode of Saturday Night Live, musical guest Paul Simon turned up on "What Up With That?," one of the show's most reliably amusing recurring skits in recent years. This sketch wasn't quite like the others, though. Whereas most of them follow a simple formula – Kenan Thompson's talk-show-host character Deandre Cole spends far too much time in his show singing his theme song, resulting in regular guest Lindsey Buckingham getting bumped at the last minute – Simon went meta and pushed the host to chat with the Fleetwood Mac guitarist. Of course, then the real Lindsey Buckingham turned up and things got even more silly. Check it out.
