shit! I don't remember to see any of these episodes. Although, I'm already laughing with these quotations you said
this must be awesome, because The Godfather trilogy are my favorite movies (part 3 not that much) and Simpsons is my favorite tv show.
I think I may have seen these episodes, maybe all of them, but I watch Simpsons daily as far back as I remember and I just watched the Godfather for the first time this year, so I may have watched them and I didn't get the jokes.

PS: don't you think that before start watching TV at all, people should watch The Godfather? is amazing how many quotations are there about it. I have seen in Seinfeld, analyze this, that's 70 show, my wife and kids, you've got mail and som others
