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!

Lisa: Dad, I think he's an ivory dealer! His boots are ivory, his hat is ivory, and I'm pretty sure that check is ivory.
Homer: Lisa, a guy who's got lots of ivory is less likely to hurt Stampy than a guy whose ivory supplies are low.

Homer: Marge, where's that... metal... dealy... you use to... dig... food?
Marge: You mean a spoon?
Homer: Yeah yeah yeah!

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!

Homer: Aw, twenty dollars? I wanted a peanut!
Homer's Brain: Twenty dollars can buy many peanuts.
Homer: Explain how!
Homer's Brain: Money can be exchanged for goods and services.

Oh Marge, you came and you found me a turkey on my vacation away from worky.

Homer: Alright brain. You don't like me and I don't like you. But let's just do this and I can get back to killing you with beer
Homer's Brain: It's a deal.

Moe: I brought you a little present. (Gives Homer a can of beer)
Homer: No. Beer bring pain.
Barney: I can't stand to see him like this. (Shoves a pillow in Homer's face. He than lifts up a water fountain, throws it at a window, jumps out and runs away)
Moe: He really needs a girlfriend.

Just squeeze your rage into a bitter little ball and release it at an approprate time. Like that day I hit the referee with a whiskey bottle. Remember that, when daddy hit the referee?

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.

Mmm... free goo.
