there have been numerous pink floyd references in the simpsons. Such as homer getting hit by peter framptons floating pig to which he replies "i bought that at pink floyd's yard sale!", and when ned flanders is high he see's the marching hammers. When homer is getting stoned off of toads he hears marge say "hello homer, is there anybody in there?" reminescent of comfortably numb.

But i guess i don't take things that seroiusly, and think about it that deeply. The newer episodes (5-11) make me laugh more, but the brand new ones are getting pretty (for lack of a better word) dumb.
