David Letterman signed off Wednesday night with his last Late Showbroadcast, ending 33 years in late-night television. “It’s beginning to look like I’m not going to get the Tonight show,” Letterman joked. A long line of celebrities appeared to offer tributes and deliver Letterman’s final Top 10 list. Letterman’s favorite band, Foo Fighters, played Letterman’s favorite song after he said goodbye. “That’s pretty much all I got,” he said. “The only thing I have left to do, for the last time on a television program: Thank you and good night.”
