Well apparently so, because it's actually a South Park quote.
(the episode goes on to explain that just about anything they do can be compered to Simpsons, kind of similar to Universal with Disney)
Bill is great in his element, which was definitely not the case for Ellen's Energy Adventure. Two amazing people in one awful ride. Arguably that's Disney's fault. But it'd be hard to make a ride with Bill being Bill fit in the parks, what I mean is it's basically taking him out of his element.
