Whenever I have one of these moments, I'm reminded of that Simpsons episode where Mo turns the bar into Moe's Family Feedbag restaurant. It's decorated like an Applebees or something (you know, with all the junk on the walls) and Marge says, "An Alligator wearing sunglasses? Now I've seen everything!"
Well Marge, you haven't seen Ukulele Dick and his Jugband doing Motown covers. Yup, you sure haven't.
Ok. Now you have, but imagine what they sound like! Personally, I'd love to hear the bass line to "My Girl" played out of a jug!
