Favourite episode is the homer they fall:
Homer: You used to be a boxer just like me?
Moe: Yup. They called me Kid Gorgeous. Later on, it was Kid Presentable. Then Kid Gruesome. And finally, Kid Moe.
--------
Moe: Yeah, he was my manager. Back when I was Gorgeous, everybody wanted a piece of me. But somehow, I just never made it to the big time.
Homer: Why not?
Moe: 'Cause I got knocked out forty times in a row. That, plus politics. You know, it's all politics.
Homer: Lousy democrats.
-------------
Marge: Night vision goggles? A bathroom scale from a soviet sub? A suede briefcase case? Anyone who needs this kind of status symbol must have some terrible emotional problems.
Homer: Marge, look! "The world's best jacket." If I had this, it would show everybody! [angrily] Show everybody!

Comic Book Guy: Yes, finally! I would like to return your quote-unquote Ultimate Belt.
Raphael: I see. Do you have a receipt, quote-unquote, sir?
Comic Book Guy: No, I do not have a receipt. I won it as a door prize at the Star Trek Convention, although I find their choice of prize highly illogical, as the average Trekker has no use for a medium sized belt.
Raphael: Whoa, whoa! A fat, sarcastic, Star Trek fan. You must be a devil with the ladies.
Comic Book Guy: Hey, I...uh, de—oh...
Raphael: Gee, I hate to let you down, Casanova, but, uh, no receipt, no return.
Bart: I'll give you four bucks for it.
Comic Book Guy: (sighs) Very well. I must hurry back to my comic book store, where I dispense the insults rather than absorb them.
