>>136829781I agree with all that except the Kim Bassenger/Alec Baldwin one and the one with Kid Rock are pretty old, and Marge making out with that woman was a fantasy in Homer's head.
I think the thing with the older episodes is that, while they did have celebrities here and there, they never glorified them and they often made them look stupid. The one with Mel Gibson involves him being dumb enough to let Homer write his next film and even has him getting run over at one point. There is however that one Krusty reunion episode that is just a half hour of jerking off the celebs, but lets ignore that one.
