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!

Homer: Aw, twenty dollars? I wanted a peanut!
Homer's Brain: Twenty dollars can buy many peanuts.

(to Marge) You promised Lisa to help her with her costume. You made her cry. Then I cried. Then Maggie laughed...she's such a little trooper!

Marge: Lisa, watch out for poison ivy. Remember, leaves of three, let it be.
Homer: Leaves of four, eat some more! (Laughs)

First you didn't want me to get the pony, now you want me to take it back, make up your mind!

Homer: Marge, please, old people don't need companionship. They need to be isolated and studied so it can be determined what nutrients they have that might be extracted for our personal use.
Marge: Homer, would you please stop reading that Ross Perot pamphlet?

Homer: Marge, try to understand. There are two kinds of college students: jocks and nerds. As a jock, it is my duty to give nerds a hard time.

Mr. Burns: (reading Homer's letter) "Dear Mr. Burns. I'm so glad you enjoyed my son's blood, and your card was just great." Why Simpson, you've made my day, you're a true gentlemen.
Homer: Well I-
Mr. Burns: Hello, there's more. (continues reading) "In case you can't tell, I'm being sarcastic. You stink! You are a senile bucktoothed old mummy with bony girl arms and you smell like an elephant's butt!"

The Monorail Song
Lyle Lanley: Y'know, a town with money is like a mule with a spinning wheel. No one knows how he got it and danged if he knows how to use it!
(audience laughs)
Homer: Heh heh! Mule.
Lyle Lanley: The name's Lanley. Lyle Lanley. And I come before you good people tonight with an idea. Probably the greatest... Aw, it's not for you. It's more of a Shelbyville idea.
Mayor Quimby: Now wait just a minute! We're twice as smart as the people of Shelbyville! Just tell us your idea and we'll vote for it!
Lyle Lanley: All right, I tell you what I'll do. I'll show you my idea! I give you the Springfield Monorail! (audience gasps) I've sold monorails to Brockway, Ogdenville, and North Haverbrooke, and by gum, it put them on the map!
Well, sir, there's nothing on earth
Like a genuine,
Bona fide,
Electrified,
Six-car
Monorail! ...
What'd I say?
Ned Flanders: Monorail!
Lyle Lanley: What's it called?
Patty & Selma: Monorail!
Lyle Lanley: That's right! Monorail!
(crowd chants "Monorail" softly and rhythmically)
Miss Hoover: I hear those things are awfully loud.
Lyle Lanley: It glides as softly as a cloud.
Apu: Is there a chance the track could bend?
Lyle Lanley: Not on your life, my Hindu friend.
Barney: What about us brain-dead slobs?
Lyle Lanley: You'll all be given cushy jobs.
Grampa: Were you sent here by the devil?
Lyle Lanley: No, good sir, I'm on the level.
Chief Wiggum: The ring came off my pudding can.
Lyle Lanley: Take my pen knife, my good man.
I swear it's Springfield's only choice...
Throw up your hands and raise your voice!
All: Monorail!
Lyle Lanley: What's it called?
All: Monorail!
Lyle Lanley: Once again...
All: Monorail!
Marge: But Main Street's still all cracked and broken!
Bart: Sorry, Mom, the mob has spoken.
All: Monorail!
Monorail!
Monorail!
Monorail!
Homer: Mono... D'oh!

Manure for sale!

Sylvia: My horoscope told me I would meet the man of my dreams today.
Homer: Well, a horoscope wouldn't lie to a pretty girl like you.
