(Bart prank calls Moe's from Principal Skinner's office.)
Bart: Hello? Is Homer there?
Moe: Homer who?
Bart: Homer… (Lowers his voice) …Sexual.
Moe: Wait one second. Let me check. Uh, Homer Sexual? Uh, come on. Come on. One of you guys has gotta be Homer Sexual.
(The entire bar laughs at Moe.)
Homer: Don't look at me! (Laughs)
Moe: Oh no... you rotten little punk, if I ever get a hold of you, I'll sink my teeth into your cheek and rip your face off!
(Principal Skinner takes the phone from Bart.)
Principal Skinner: You'll do what, young man?
Moe: What--what? Wait. Who--who is this?
Principal Skinner: I think the real question is who is this and where is Homer Simpson?!
Moe: Whoa, whoa. Sorry. Principal Skinner, sorry. It's--it's a bad connection, I think. (Hands phone to Homer.) Gah, it's for you. I think Bart is in trouble again.
Homer: D'oh!

(At Moe's, Patty interrupts Selma and Barney's date.)
Selma: Patty, are you throwing away your last chance at happiness just for me?
Patty: Yes.
Selma: Oh. Thanks.
Patty: Now, let's go get some pancakes.
Selma: Uh, listen, Barney, uh... Aah.
(Patty and Selma get up and leave.)
Barney: She broke my heart, Moe. (Sobs)
Moe: Don't worry, Barney. Time heals all wounds.
Barney: (Sees a full pitcher of beer.) Well, what do you know? You're right! And, look, a whole pitcher to myself!

(Marge orders Homer to find Selma a man fit to be her husband.)
Marge: Homer, you will find her a man!
Homer: All right.
Marge: And not just any man.
Homer: Okay.
Marge: He should be honest and, and caring and well off and handsome!
Homer: Hey, why should she have a better husband than you do?

In the shot of Skinner checking his tater tots, he is interrupted and lifts his tray. As he inspects it, he tilts his tray to at least a 90 degree angle but everything, including the milk, stays in exactly the same spots and do not fall off.
