Wait! I need closure on that anecdote.

Squeaky-Voiced Teen

Homer: Lisa you're smart, help me trick her into taking me back!
Lisa: Dad, you can't trick somebody into loving you. There's a reason two people come together and stay together - there's something they give each other that nobody else can give them. If you wanna get Mom back, you'll just have to remember what you give her that no one else can.
Homer: I'll pay you forty dollars if you think of it for me.
Lisa: No.
Homer: Okay thirty.

(After an insect falls out of his hair) You think you get them all, but you forget about the eggs.

Homer: (playing poker, gagging and coughing up poker chips) Ew! Don't try to eat these so called "chips".
Moe: Are you gonna take some cards, or not?
Homer: Oh...yeah.
(takes four cards)
Homer: D'oh! D'oh! D'oh! D'oh! Er, I mean, "woo hoo".
Moe: I'm in.
Homer: Aww, I was bluffing.
(lays out cards)
Moe: Ha, ha, ha! Come to papa!
(takes chips and looks at cards)
Moe: What? You have a straight flush, Homer! Ya do this every time! Arrrgh-eeengh-gah! Choking on my own rage here!

What is a wedding? Well, Webster's Dictionary defines a wedding as, "the process of removing weeds from one's garden."

Homer

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: Oh. And how is education supposed to make me feel smarter? Besides, every time I learn something new, it pushes some old stuff out of my brain. Remember when I took that home wine-making course and I forgot how to drive?
Marge: That's because you were drunk!
Homer: And how.

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!

Lisa: Will you be lecturing from a standardized text or using the more Socratic method of interactive class participation?
Homer: Yes, Lisa. Daddy's a teacher.

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.

If he can teach a class, then he can teach a class! I mean, I can teach a class!

Homer

Annex Manager: Now Tell me Mr. Simpson, what special skills could you teach a class on?
Homer: Uh... I can tell the difference between butter and I Can't Believe It's Not Butter.
Annex Manager: No you can't! No one can!

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.
