The Top 10 David Letterman Top 10 Lists [VIDEO]

Last night, David Letterman celebrated 20 years as the host of "The Late Show" with a visit from his first-ever guest, Bill Murray.

More than anything, Letterman's late-night show is known for its Top 10 lists. In honor of 20 years of Letterman, we decided to pull together our own Top Ten list of Letterman's Top Ten lists.

To compile the ranked list, we took into consideration top-viewed lists from YouTube and talked-about lists across the Internet. We also looked at prior anniversary lists from Letterman himself.

We also turned to CBS' archives of top 10 lists dating back to mid-2000. Not all of our selections have video.

Without further ado, these are the lists that had us laughing the hardest:
