“Oh, recycling is useless, Lisa. Once the sun burns out this planet is doomed. You’re just making sure we spend our last days using inferior products.”
“I must only use this power to annoy!”
Bart’s brain: “She’s beautiful. Say something clever.”
Bart’s mouth: “I fell on my bottom.”
Strangely, I tend to use that one quite often. I’m not so sure what that says about me, but there you go.
“Eep”
I use that too much.
Bart:(playing Scrabble with his family) K-W-Y-J-I-B-O…Kwyjibo. 22 points…plus 50 points for using all my letters! Game’s over, I’m outta here…
Homer: Wait a minute, you little cheater–you’re not going anywhere until you tell me what Kwyjibo is!
Bart: Kwyjibo? Uh… a big, dumb, balding North American ape with no chin…
Marge: And a short temper!
Homer: Why you little! (starts chasing Bart)
Bart: Uh oh, Kwyjibo on the loose!
Used more than once, I believe:

“We’ll live like kings! Damn hell ass kings!!”
Well, of course the immortal, deadpan “Eep” is Bart’s best line. Among his other good ones however:
Homer is trying to come up with an anchor for the speeding monorail, and looks at bart, seeing him as an anchor
Bart: Think harder Homer.
Lisa: Nirvana
Bart: A state of bliss obtained throught extinction of the self.
Bart: I’m gonna fool you good Homer!
Brad Goodman: What’s your name son?
Bart: Rudiger
Bart: Then, if I know my geography, it’s only 12 miles to Africa
Homer: Now, do you think you can stop the casual swearing?
Bart: Hell yes!
(from the episode where Homer flees to a Pacific island as a missionary to escape the PBS Pledge Enforcement Squad)
Rupert Murdoch, on the Fox TV telethon: “$20 million? You’ve saved my network!”
Bart: “Wouldn’t be the first time!”
