There's not a clip anywhere I can find. It's like you have to find the whole damned episode somewhere on a torrent site.
You realize that Kaufman was gaslighting everyone, and that was the point of the bit, right? He loved heel wrestlers, and the entire "intergender championship" was a build on him as a wrestling heel? It's a major plot point covered in the biopic "Man in the Moon", etc.
That's why I mentioned him in this... unless Chappelle reveals out of nowhere this has been a bit to pull the rug out of truly intolerant people, a la Kaufman posthumously, or say, Sasha Baron Cohen tricking conservatives into being themselves and saying what they really think as Borat... it's just not a joke.
