(Kent Brockman reports on the Springfield presidential primary.)
Kent Brockman: With Springfield's primary now first in the nation, our humble city is overrun with candidates, newshounds, spin doctors, hacks, flacks, Russerts, Blitzers and even the occasional voter. (to Moe) Sir, do have a preference?
Moe: Yeah, I like girls, fruit loop.
Kent Brockman: Oh. Are you a registered voter?
Moe: I'm a registered… something.
(An alarming amount of presidential hopefuls descend on the Simpson house when they see that the Simpsons haven't decided who to vote for yet.)
Homer: If you haven't sprung from or aren't married to my loins, get the hell out of this house!
(All the candidates leave, except for someone hiding behind a plant.)
Homer: You too, Fred Thompson!
Fred Thompson: But I was in Die Hard.
Homer: (Scoffs) Die Hard Two!
Nelson: (to Washington Post reporter) Haw-haw! Your medium is dying!
Principal Skinner: Nelson!
Nelson: But it is.
Principal Skinner: There's being right and there's being nice.
