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!

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

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!

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!

(After Homer rejects other names for boys based on rhyming nicknames)
Marge: What about Bart?
Homer: Let's see. Bart, dart, cart, e-art. Nope can't see any problems with that.
(Missing fart due to only 4 fingers)

(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!

Homer: There's a $10,000 bill in it for you.
Barney: Oh yeah? Which president's on it?
Homer: Uh, all of them. They're having a party. Jimmy Carter's passed out on the couch.

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.

Ned Flanders: We're done for, we're done-diddly done for, we're done-diddly-doodily, done diddly-doodily, done diddly-doodly, done diddly-doodily!
Homer: Flanders! Snap out of it!

Go love making!

Marge & Homer

Homer: I never passed Remedial Science 1A.
Marge: And you're a nuclear technician?
Homer: Marge! Ix-nay on the uclear-nay echnician-tay. (Speaking in Pig Latin)
Marge: What did you say?
Homer: I dunno. I flunked Latin, too.

Firefighter: You've horribly injured the whole fire department!
Homer: Who are you, a travel agent? 'Cause you're sending me on a guilt trip!
Firefighter: Sorry.
