these are just the tip of the iceberg. all dialogue is not word for word, but you'll get the point.
1)When homer and moe et.al start the pin pals bowling league. The scene when moe says something to the effect,"I'm tired of getting treated like dirt...well....not that fancy store bought dirt, it is loaded with nutrients and minerals"
2)the mary bobbins episode. at the very end when she flies away and barney shows up out of no where and says "BYE SUPERMAN".
3)the scene when homer makes the fake dummy of himself and it falls down the waterfall and lenny and carl narrate the contradictory series of events.
4)the scene where mr. burns is looking for someone to play the role of him in his move....homer comes out with the intention of doing mr. burns trademark "exc-ellent" and instead he says "ex-act-ly" followed by a prompt...DOH!
5)the scene where moe arranges homer to steal his car. they are at the police party on the ship and moe, nonchalantly (says something to the effect of) to chief wiggum,"hey, look at my parking job over there" and the chief says, what the one with the big rubber daisy? and then he says, with excitement...hey yeah that is a great park job...then he looks up at lou(another cop) and says hey lou look at the park job in space _____? and lou replies with all sincerity....yeah, that's sweet.
6)the episode where homer had the pet lobster and he was taking it for a walk on the beach and it cowers from a hermit crab. then homer says to his lobster, "you don't have to take that from that punk ass crab!"
7)the scene where groundskeeper willie rips off his shirt and tells lunch lady doris.."grease me up woman!"
8) the episode when homer gets the sexual harassment charge after he grabs the gummy venus off some babysitters butt. Then when they show his interview on tv it is all hacked up to portray that he was guilty...... notice the clock in the background....
9)the scene with john waters where john waters tells bart and lisa that in japan they call santa claus,"the annual gift man, who lives on the moon".
10) the episode where marge tells homer not to cuss and he makes a swear jar. homer is making a doghouse, he impales his foot on a nail sticking from a board...he cringes and says(struggling to refrain from cursing) "Oh diddly dee.....that will require a tetanus shot".
that is enough. these are NOT my top 10 just the first 10 that popped in my mind. i could go on forever.
