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

Homer

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!

Receptionist: Hello, sir. Are you here for "Coping With Senility?"
Jasper: No. I'm here for "Microwave Cookery" ... No, wait, "Coping With Senility."

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: 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.

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!

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

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.

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)

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!

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!
