Veggie-tunes nut - he's not alone! There's an entire Vegetable Orchestra

The beginning part was interesting - watching them make the instruments. But after (ok, maybe during) their first "song" they mostly just played sounds that must be up there in the ranks of the world's most annoying noises, so save yourself the frustration (and increase in blood pressure) and just stop watching when you start to get irritated, it doesn't get any better, trust me.
