I don't know what you guys want, the episode amused me profoundly. The Herzog bit was a nice surprise. I liked the first inter-dimensional TV episode better though.
Definitely weak, but even a bad R&M episode is a good one.
If nothing else, there's always cool background **** to look for, like the gerbil-living-in-an-ass walking out disgusted during the "personal space" show, and the alien dude behind him counting along with the host like it was the best thing ever.
