Chalkboard: None

Couch: Repeat of the couch gag from "Scenes from a Class Struggle in Springfield" where The Simpsons are shown in fluorescent colors under a blacklight.

Bart: Dad, you cannot wear that! That's a Rastafarian hat.
Homer: Pft! Hey, I've been safariing since before you were born.
Lisa: Wearing a Jamaican hat makes a bold statement about your connection to reggae music.
Homer: Well, excuuuuuse me!
(sticks a sticker on his hat that says "Too cool for this planet")
Bart: You know what, dad? Maybe we'll go exploring on our own for a while.
(the kids run away)

Marge: So… you want to go on tour with a traveling freak show.
Homer: I don't think I have a choice, Marge.
Marge: Of course you have a choice.
Homer: How do you figure?
Marge: You don't have to join a freak show just because the opportunity came along.
Homer: You know, Marge, in some ways, you and I are very different people.

(In a flashback, Grampa Simpson catches Homer and Barney singing and dancing in Homer's room.)
Grampa: What the hell are you two doing?
Barney: It's called rockin' out!
Homer: You wouldn't understand, Dad. You're not "with it."
Grampa: I used to be "with it." But then they changed what "it" was. Now what I'm "with" isn't "it" and what's "it" seems weird and scary to me. It'll happen to you.
Homer: No way, man. We're gonna keep on rockin' forever.
