Chalkboard: Loose teeth don't need my help

Couch: Repeat of the couch gag from "The Wizard of Evergreen Terrace" where the living room is a movie theater filled with supporting characters from the show, The Simpsons shuffle their way to the couch, and Homer eats some of the Comic Book Guy's popcorn.

Lisa: Now we're pulling into port … and who's waiting for us at the dock? Why, it's all your childhood dogs! I see Petey, and Blackey, and Schnoodle …
Bart: Oh no! Pirates!
Jasper: Pirates!?
Bart: Ahoy Mateys, it's me, Long Bart Silver. And I'm gonna rip you a new IV hole.

Students: Children, children,
Future, future.
Milhouse: Are you ready for the...
Students: ...children, whoa whoa whoa!
Lisa: The future is a...
Students: ...coming, hey hey hey!
Children, children,
Future, future
...
Students: Children, children,
Children are the future!
Kids!

Bart: What are you gonna do to me?
Principal Skinner: Bart, not all Community Service is gang warfare and dangerous infection, and to illustrate that point here's where you'll be working.
(Principal Skinner points in the direction of a storefront)
Bart: The Fireworks, Candy, and Puppy dog store!?
Principal Skinner: No, no, no. Next to it.
(Jasper and Old Jewish Man are sitting outside. Grampa comes out)
Grampa: Settle a bet: Boil or mole?

(In the kitchen, Homer is frying some hamburgers.)
Homer: Welcome to the kitchen of tomorrow ... today! Marge, how much would you pay for a self-flipping hamburger pan?
Marge: Nothing.
Homer: Don't answer yet. Watch how easy it is to flip hamburgers with the help of God's greatest creation ... the spring!
(Homer has attached springs to the bottom of a pan. Homer uses them to flip it. The burgers fly up vigorously, and then land right back on the pan, splattering grease everywhere. Then the grease sets on fire. Homer screams, and starts rolling around on the kitchen floor, trying to put the fire out. Marge gets the fire extinguisher, and puts out the curtains, the pan, and Homer...in that order.)
Marge: Are you okay?
Homer: Some second-degree burns…but some first-class burgers!
