It's from "Mr. Jones" by Mike Jones. I'd never heard of it till I searched online, but the video has been watched almost 3,000,000 times on youtube, so I guess I'm just old and out of it.
In other player music soundbite news, to make sure I have 300 characters, I would swear I heard the Flinstones theme song when Roy scored today. Anyone else hear that? And am I missing an obvious connection there?
