David Letterman's most memorable guests

After 33 years of late-night-talk-show fame, David Letterman will take his CBS stage one final time on Wednesday night. From 1982 to 1993, Letterman hosted Late Night with David Letterman and moved to CBS in late 1993 to host the Late Show. On both shows, on both stages, Letterman has chatted with some of the most famous people in the world, from actors to presidents to Major League Baseball teams.
