Jack Black is one of my favorite comedians. He has the unique talent of taking any mundane situation and turning it into something hilarious. Put Jack and David Letterman’s famous Top Ten lists together, and you’ve got pure comic gold.

This bit from The Late Show has Jack in a music store, demonstrating the top ten things that you don’t want to hear when shopping there. Things like, “You look kind of Garfunkelly.” How original is that?

They’re all quite funny, but my personal favorite is number one. The victim of the prank looks like he can’t decide whether he’s confused or amused, but best of all we get to hear Jack sing. And that’s always a treat.
