In less than one week, David Letterman will make his last appearance as the host of the Late Show.

It's hard to believe that he's been in the gig for 33 years—that's over 6,000 broadcasts and nearly 20,000 total guest appearances—and he's already picked who will join him onstage during the final few episodes.

It was just announced that Tom Hanks, Bill Murray and Eddie Vedder will be among the final guests of the hit late-night show.

The three-night sendoff will begin on May 18 with a visit from Hanks, marking his 60th appearance on the show, followed by the Pearl Jam frontman.
