Chalkboard: Mud is not one of the 4 food groups

Mr. Burns: We both want a fair union contract.
Homer: (thinking) Why is Mr. Burns being so nice to me?
Mr. Burns: And if you scratch my back, I'll scratch yours.
Homer: (thinking) Wait a minute. Is he coming onto me?
Mr. Burns: I mean, if I should slip something into your pocket, what's the harm?
Homer: (thinking) My God! He is coming onto me!
Mr. Burns: After all, negotiations make strange bedfellows. (chuckle, wink)
Homer: (thinking) Aaahh! Sorry, Mr. Burns, but I don't go in for these backdoor shenanigans. Sure, I'm flattered, maybe even a little curious, but the answer is no!

Boy: You can't treat the working man this way. One day we'll form a union and get the fair and equittable treatment we deserve. Then we'll go too far, and get corrupt and shiftless and the Japanese will eat us alive!
Mr. Burns' Grandfather: The Japanese!? Those sandal-wearing goldfish tenders? Bosh! Flimshaw!
Years Later
Mr. Burns: If only we'd listened to that boy, instead of walling him up in the abandoned coke oven.

Mr. Burns: Now, let's get down to business.
Homer: (thinking) Oh, man. I have to go to the bathroom. Why did I have all that beer and coffee and watermelon?
Mr. Burns: Now Homer, I know what you're thinking. I want to take the pressure off. Now, it doesn't take a "whiz" to know that you're looking out for "Number One". Well, listen to me, and you'll make a big splash very soon.
Homer: Ooh, which way to the bathroom?
Mr. Burns: Oh, it's the twenty-third door on the left.

Grampa: One trick is to tell 'em stories that don't go anywhere, like the time I caught the ferry over to Shelbyville. I needed a new heel for my shoe, so, I decided to go to Morganville, which is what they called Shelbyville in those days. So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on 'em. "Give me five bees for a quarter," you'd say. Now, where were we? Oh yeah, the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones..

Lisa: Come gather round children, it's high time ye learns,
'Bout a hero named Homer and a devil named Burns.
We'll march till we drop, the girls and the fellas.
We'll fight to the death or else fold like umbrellas.
So we'll march day and night by the big cooling tower.
They have the plant, but we have the power.
