Supercut of David Letterman asking the drummer if those are their drums

From CBC:

David Letterman is really into drums. There’s a thing he sometimes does after a band plays on his show: he walks up to the drummer, compliments them on their drums and asks if they’re rentals. The CBC noticed it happening often enough that they combed YouTube for a few dozen instances and created this supercut of Letterman talking to drummers.
