Ukuleles: Automatic Happiness!

Tom McRae isn't known for being a ukulele player, to my knowledge -- most of what I've heard (ex., "The Ballad of Amelia Earhart," "Me and Stetson") is complex, melancholy-ish, lyrical alt-something. But this popped up on a YouTube search, and not only is it a great song, but the audience interaction gets kind of hilarious.
