Man, there are so many episodes I like, it is hard choosing a single one. I don't know why, but I really like the one where Homer accidentally invents "Tomacco" and everyone goes crazy. A cigarette company offers him 150 million for it, he says he won't take anything less than 150 billion, and they end up getting it for free. I'm sure if I went through all of the episodes I could come up with one I enjoy more, but that's the first one that comes to mind. Do you have any favorites? Pugs
