Bart Simpson, that is a rebuilt Yugoslavian engine and there's not even a Yugoslavia anymore. Bring it back at once.

Skinner: It will be featured in the fifth grade play of the Crucible.
Superintendent Chalmers: Good seats still available and by that I mean seats in the back where you can fall asleep.

Principal Skinner: The fifth grade will now favor us with a scene from Charles Dickens' Christmas Carol.
Homer: How many grades does this school have!?

Ah, the fourth grade will now favor us with a melody...err...medley of holiday flavorites.

Principal Skinner: Whoever did this is in very deep trouble.
Martin: And a sloppy speller too. The preferred spelling of "wiener" is 'W-I-E-N-E-R', although 'E-I' is an acceptable ethnic variant.

Principal Skinner: Actually, he'd be staying in France, in a lovely chateau in the heart of the wine country.
Marge: But Bart doesn't speak French.
Principal Skinner: Oh, when he's fully immersed in a foreign language, the average child can become fluent in weeks!
Homer: Yeah, but what about Bart?
Principal Skinner: I'm sure he'll pick up enough to get by.

Principal Skinner: Mr. and Mrs. Simpson, we have transcended incorrigible. I don't think suspension or expulsion will do the trick. I think it behooves us all to consider...deportation.
Marge: Deportation? You mean kick Bart out of the country?
Homer: Eh, hear him out, Marge.

Principal Skinner: Tonight Sherbert's, heh, heh, Shubert's Unfinished Symphony.
Homer: Oh, good, unfinished. This shouldn't take long.

Principal Skinner: Welcome to the first in a series of Saturday evening concerts.
Homer: Series? Awww.

Lisa Simpson in detention? My horoscope told me I'd see something interesting today, but I thought that'd be the horoscope itself

The Simpsons Quotes

Homer: (Wearing glasses) The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side!
Man: (From inside a bathroom stall.) That's a right triangle, you idiot!
Homer: D'oh!

Son, a woman is a lot like a... a refrigerator! They're about six feet tall, 300 pounds. They make ice, and um Oh, wait a minute! Actually, a woman is more like a beer. They smell good, they look good, you'd step over your own mother just to get one! But you can't stop at one, you wanna drink another woman!
