Wow. I watched it just thinking Holy Crap, this is weird! It was sort of funny, I guess. What was odd was that it looked like it was written by someone trying to take the mickey out of the show, but they'd never heard it. Which is odd, as John is a "friend of the show".
It seemed like they were trying to make fun of the crassness of the show, when Chris really wouldn't fart on the show. OK, he does burp now and again.
Very disconcerting seeing the team, as they have the outfits spot on, but not the actual bodies! (from left to right) Fat-Dom, Fat-Tina, Taller-and-No-Fivehead-Aled and Looks-Nothing-Like-Dave-So-We'll-Hide-His-Face.

I haven't heard Thursday's show yet. Did they mention it?
