Turns out, you can make a lot of famous friends when you host a show for 33 years. David Letterman is retiring from the Late Show [1], but at least he's going out with a bang. CBS has announced the lineup for the final 28 episodes of his run on the show, which will conclude on May 20. Sarah Jessica Parker [2] kicked off the last of the broadcasts on Monday night, and the stars will continue to roll in to bid adieu to the late-night legend for the next month. Here's the full list of who to expect to pop up on the upcoming shows: Alec Baldwin [3], George Clooney [4], Billy Crystal, Robert Downey Jr., Will Ferrell [5], Tina Fey [6], Michael J. Fox [7], Tom Hanks [8], Jack Hanna, Kevin James, Scarlett Johansson [9], Michael Keaton, Steve Martin [10], Bill Murray [11], Don Rickles, Julia Roberts [12], Ray Romano, Paul Rudd [13], Jerry Seinfeld [14], Martin Short, Howard Stern, John Travolta [15], Bruce Willis [16], Oprah Winfrey [17], Elvis Costello, Dave Matthews Band, John Mayer [18], Mumford & Sons, and Tom Waits.
