SNL stole a page out of the 30 Rock handbook by having a bunch of celebrities show up to sing Billy Joel's "Goodnight Saigon." The punchline, in edition to having Paul Rudd faking violin skills, is that host Will Ferrell isn't singing about the Vietnam War, he's singing about a pretty sweet vacation he had a few years ago. A bunch of stars, like Norm MacDonald, Rudd, Maya Rudolph, Anne Hathaway, Amy Poehler and others help out at the end, but for some reason Artie Lange gets the biggest applause. [Videogum]
