Well, Beavis and Butthead have made it into Saturday Night live. It's only about 45 minutes into the show right now, and I've counted 4 references. #1 was the guitar player playing the B&B theme (from the very beginning). #2 was how "Larry King" and that other guy were laughing. #3 was during Hollywood Minute, and #4 was the "Beavis and Dickhead" part of Weekend Update.
Sure, #2 is weak, but you can tell that they're infiltrating the writing staff of SNL.
