You remember Rhett & Link's crazy ad for Chuck Testa's Ojai Valley Taxidermy—you know, the one that stuffed the entire Internet. It was their biggest hit so far (even bigger than the Cullman Liquidation spot, which Errol Morris called the best commercial ever). Well, the Gregory Brothers liked the Chuck Testa ad, too—and so they songified it. Check out their video below. It's good, but it's actually not much funnier than the real thing. Which is a testament to Rhett & Link, really. You can't really improve on genius. Also below, check out the Fine Brothers video "Kids React to Chuck Testa," which itself is referenced in the Gregory Brothers clips.
