Late Show with David Letterman

Piedmont Bird Callers, Hank Azaria, Maria McKee

Rather than come out of nowhere, Dave orders the muscle guy to pummel Alan; during a segment called "Summertime Leftovers," Dave once again shows footage of his "look-alike" (himself, circa his morning show) playing "Camptown Races" on the fiddle; Simpsons star Hank Azaria plugs America's Sweethearts.
