Following the death of the Casey Kasem, all corners of the internet have been scoured for video of the legendary entertainer. Well, the Late Show with David Letterman just unearthed a gem of a clip from 1993 that featured the 'countdown king' doing the countdown with Letterman.

Kasem is known for many things, but the American Top 40 is his biggest claim to fame. Millions can remember listening to Kasem count down the hits each week on the radio. In this video, Kasem counts down (with Dave) his Top 10 Favorite Numbers.

Trust me, this is hilarious.

RIP Casey Kasem.
