[last lines of the episode, as the Griffins sit on the couch after Peter apparently fixed the timeline]
Lois Griffin: Wow, Peter, that's an amazing story. And I'm touched that you went through so much trouble just to be with me. Obviously, I made the right choice when I married you.
Peter Griffin: Me, too, Lois. And, hey, let's just all be grateful that things are completely back to normal again.
[Roger from "American Dad!" walks up to the Griffins]
Roger Smith: Who ate all the pecan sandies?
Brian Griffin: [to 18-year-old Lois in 1984] I would eat your poo.
Marvin: [on the phone] Hey Rick, it's Marvin. Your cousin, Marvin Astley. Remember that mediocre, generic sound you were looking for? Well, listen to this!
[the Jetsons opening sequence is shown, but when Jane leaves with George's wallet, George puuls Jane back in the flying car]
George Jetson: Hey, hey, hey, hey! No, no, no. no! I took this one out for you! You take that one, I take this! You are not taking my whole wallet just so you can go shopping!
Jane Jetson: I was just going to buy some groceries.
George Jetson: Bullcrap!
Peter Griffin: Well, Rusty, looks like we're gonna eat our way out of another jam.
Brian Griffin: Hey, I like your dress.
Woman: Get lost, jerk. I'm here with my boyfriend.
Brian Griffin: You mean that quintessential '80's guy, with his collar turned all the way up?
Man: [With a ridiculously high collar] Hey, are you hitting on my girlfriend?
Brian Griffin: No, I was just being friendly.
Man: I can kick your ass, anywhere, anytime!
Brian Griffin: Okay, how about on top of the World Trade Center, September 11th, 2001 at 8 am?
Man: I will be there, pal. You think I'll forget, but I won't!
[after Brian perform's Rick Astley's "Never Gonna Give You Up"]
Man: I didn't like any of that.
Ms. Pac-Man: WHAT? WHAT?
Ghosts: [backing away from Ms. Pac-Man] Geez, nothing. B*tch!
