Meg: Hey, I'm back from Lake Disappointment, Australia. The water there was salty and undrinkable.
Peter: That's why it's called that, and you're a disappointment too.
Meg: Yeah, dad, real classy. Can you just stop being an ass for once?
Peter: I'm just telling it like it is, Meg. You suck.
Lois: Peter, stop it. Meg, I'm sorry about his behavior. He's a moron.
Brian: Yeah, Peter, lay off. You're being a real dick.
Stewie: Oh, look who's talking, the guy who licks his own balls. Real classy, Brian.
Chris: Hey, guys, can we all just get along? Meg, I hope you had a good time despite the salty water.
Meg: Thanks, Chris. It's good to be back, I guess.
Peter: Yeah, whatever. I'm gonna go get a beer. You guys sort out your own disappointments.
