A few months ago Lancelot and I were introduced to this by bort at Nondiscovery Blog. Since then we have burned hundreds, maybe even thousands of calories, laughing or asses off at it. It's one of those that just gets funnier every time you watch. (I recommend back-to-back viewing for intense ab workout).
This clip is so damn funny that the Family Guy did a spoof on it. It's good stuff.
I hope eveyone had a happy Thanksgiving.
