Gotta love the internet. Mark Evanier posted the clip below on his blog, where the boys have their words reversed so it can sound like a foreign language. He was wondering what in the world they actually said.
Less than nine hours later, somebody not only reversed the speech bits but then put them back in the right places so they could be truly played forwards. Then it was up on YouTube.
Update: The original clip is gone, but somebody's combined the two, so that's what you've got coming up...here:
Nothing earth shattering like "Paul is Dead" or anything, but still. Gotta love it.
