[Extended DVD scene]
Lois Griffin: Well, peter I'm glad you and the guys finally found what you were looking for.
Peter Griffin: We did. It's just sad that 230 people had to die in the most gruesome way imaginable. But our idle curiosity was satisfied so everything worked out.
Brian Griffin: Peter, you went halfway around the world for this joke but I never even got to hear it.
Meg Griffin: Yeah, me neither.
Chris Griffin: Yeah, come on dad! Tell the joke!
Peter Griffin: Alright, you guys want to hear it? Alright so this chick goes on a date with this guy she wants to fuck but she's worried cause she's got, like a huge vagina from fucking so many other guys so she gets a piece of liverwurst and shoves it up in her vagina so that when he fucks her it'll feel tighter.
Lois Griffin: Peter, maybe this isn't family conversation.
Peter Griffin: No wait, Lois shut the fuck up. So she puts the liverwurst in her vagina, goes home with the guy, fucks him, everything seems fine. She wakes up the next morning and he's gone and he's left her a note that says, "Thank you for a lovely evening. However, I don't think this is going to work out. P.S. Your vagina is in the sink." Now I'm gonna leave the room now as I have just shit myself again.
