Chalkboard: I will not do the Dirty Bird

Couch: The living room is in shallow water and the Simpsons sit on the couch. An iceberg passes by and causes it to sink (à la The Titantic) with the family clinging to the couch as it goes under. Maggie resurfaces on a couch cushion moments later with the remote control in hand.

Pat Summerall: Well John, what did you think of tonight's episode?
John Madden: I loved it! The last-minute addition of Wally Kogen to the line-up was a bit of a gamble, but it really paid off.
Pat Summerall: Marge and Lisa painting eggs? Did that work for you?
John Madden: Ho, ho, big time! They came off the bench with a huge effort that allowed Homer and Bart to make some significant gains.
Pat Summerall: Did it strike you as odd that in a Super Bowl show with Dolly Parton we didn't see any football or singing?
John Madden: I hadn't thought about it, Pat, but in retrospect, it was kind of a rip-off! What a way to treat the loyal fans, who put up with so much nonsense from this franchise.
Pat Summerall: Any final thoughts?
John Madden: Nah, I'm too mad, let's get the heck out of here!

Homer: Now, this wheel balancing is free, right?
Man: Oh, you betcha, absolutely. Deh, uh, oh, uh-oh, wait a minute. These tires won't take a balance!
Homer: They won't?
Man: Nah, nah, no, you hear that clunk?
Homer: No …
Man: Well, that tells me you need four new tires.
Homer: Really?
Man: Yeah. Legally, I can't even let you drive outta here on these.
Homer: Oh, please, can't you let me slide this time?
Man: Gee, I'd really like to, but if my boss found out, I …
(he makes a hand gesture to his boss)
Boss: All right, what's going on over here? Were you gonna let this man drive out of here on unsafe tires?
Man: No boss, I swear!
Boss: Ah, that's it, you're fired!
Homer: No! Wait! This is all my fault! Oh, if I could only turn back the clock and buy four new tires …

Homer: Come on, Lenny, I need four more guys to fill my Super Bowl bus. What do you say?
Lenny: (on phone) Naah …
Homer: Come on …
Lenny: Naah …
Homer: Come on!
Lenny: Naah …
Homer: Oh, come on!
Lenny: Oohhh …
Homer: Yes! Now that Lenny's in, Carl will fall like a domino.

Wally: Well, we sure put together a heck of a trip, Homer. Ever thought about being a travel agent?
Homer: Wally, I'd be lying if I said I hadn't.
Wally: 'Cause you can really ... "go" places in the travel business. Huh? (laughs) Feel free to use that one.
Homer: What one?
