What was David Letterman’s greatest moment?

David Letterman will be signing off of "Late Show" on Wednesday night, and after weeks (or has it been months?) of tributes, his 33-year run as a late-night TV host will be purely the stuff of memories.

We've been looking back at Letterman too. For example, his most notable interviews, including his very first interview on the very first episode of "Late Night" with Bill Murray. A history of Letterman's Top 10 Lists -- can you name the subject of the first one? A retrospective of notable guests, musical performances and shenanigans.

But enough about us. What's your favorite David Letterman memory? The greatest moment in Letterman history? Tell us in the comments below, let us know on Facebook or tweet us at @latimesent. We'll update the post as we here from you.
