Chalkboard: Today is not Mothra's day

Couch: A repeat of the couch gag from "Little Big Mom" where The Simpsons are crash-test dummies and the couch slams them into the TV as part of the test (resulting in Homer's head falling off from the trauma).

Hibbert: Oh, you're also responsible for this hefty hospital bill. You shouldn't have ordered all those hospital haircuts and porno films.
Homer: But "Doctor Screwlittle" sounded like a delightful romp. Well, you don't have to worry about the bill; we've never welched on a … look, a bear! (pointing off screen) Run! (Homer gets up to run but his knee gives way, everyone - including the bear look at him disappointed).

Homer: Ugh. Well, I can still hang out with you guys.
Bart: Sorry, I've got a baseball game in fifteen minutes.
Lisa: And I've got a rally for "Take Back the Afternoon".
Grandpa: Heh, heh, heh, so the tables have turned! Now you're the shut-in, and I'm the hip young dude. (cracking noise comes from Abe's finger) Oops, there goes my wagging finger.

Rod: Can Mr. Simpson watch us every day?
Ned: Oh, Roddy, he's not running a daycare center!
Homer: Don't tell me what I'm not doing.
Ned: So you are running a daycare center?
Homer: Oh, you'd like that wouldn't you.
Ned: Oh I sure would! It'd give the boys a place to go after school.
Homer: Then I'll do it! Just to see the look on your face (Flanders smiles) …that's the one!

Bart: Hey Homer, I thought you were only going to do this day care thing 'till your knee was better.
Homer: Yes, but then I discovered the joys of raising children.
Lisa: But what about us?
Homer: Don't worry honey; you'll have children of your own some day. Then you'll know my joy.
