(to Bart) Keep up the roughhousing, boy. Without a strong male figure, you could turn sissy overnight. (as he's scrubbing his underwear) Oh, these stubborn grass stains.

Homer

Marge: Homer I really don't like you telling personal secrets in your class.
Homer: Marge I didn't tell em personal stuff.
Marge: Today at the Kwik-E-Mart everyone knew I dyed my hair blue.
Homer: Oh you mean about you?

Well, let's just call them... uh, 'Mr. X' and 'Mrs. Y'. So anyway, Mr. X would say, "Marge, if this doesn't get your motor running, my name isn't Homer J. Simpson!"

Homer

Homer: Look Marge, you don't know what it's like - I'm the one out there every day putting his ass on the line. And I'm not out of order! You're out of order! The whole freaking system is out of order! You want the truth? You want the truth? You can't handle the truth! 'Cause when you reach over and put your hand into a pile of goo that was your best friend's face, you'll know what to do!! Forget it Marge, it's Chinatown!!!
Marge: Homer, don't ever tell them personal stuff about me again!!
Homer (sheepishly): Yes ma'am.

Annex Manager: We need someone to teach a course on how to build a successful marriage.
Homer: I'll do it! Anything to get me out of that house, away from all that nagging, and noise... uh, of a family of love. Tra-la-la-la!

Homer: Okay, brain. If we don't think of something, Marge will leave us forever!
Homer's Brain: Eat the pudding, eat the pudding, eat the pudding, eat the pudding, eat the pudding...
Homer: Well, alright. But then we gotta get to work. (starts eating the pudding)

Groundskeeper Willy: If I wanted to see a man eat an orange, I'd have taken the orange eating class.
(cut to orange eating class)
Moleman: The eating of a good orange is a lot like a successful marriage.
Grampa: Just eat the damn orange!

Homer (wearing a leather jacket): Look everyone. Now that I'm a teacher, I've sewed patches on my elbows.
Marge: Homer, that's supposed to be leather patches on a tweed blazer, not the other way around. You've ruined a perfectly good jacket.
Homer: Uh...incorrect, Marge. Two perfectly good jackets.

I can't believe I paid ten-thousand dollars for this class. What the hell was that lab fee for!?

Otto

Marge everything is a sin. Have you ever sat down and read this thing? (holds up the bible) -Technically we're not allowed to go to the bathroom.

Reverend Lovejoy

Marge: We don't think you're slow. But on the other hand, it's not like you go to museums, or read books or anything.
Homer: You think I don't want to? It's those TV networks, Marge, they won't let me. One quality show after another, each one fresher ad more brilliant than the last. If they only stumbled once, just gave us thirty minutes to ourselves! But they won't! They won't let me live!

Moe: Hey Homer, why don't you nibble her elbow...that always melts her butter, heh heh.
Marge: Get out! Everyone get out now!
Apu: Ooooh, she's got to have it!

The Simpsons Season 5 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!

You know, you remind me of a poem I can't remember, and a song that may never have existed, and a place I'm not sure I've ever been to.

Grampa
