Keitha: You couldn't get more Australian than me. My great-great-grandpa was a renowned rapist, and they shipped him out to Australia and that's where he met my great-great-grandma; she was a prostitute. You know, I said "met" but he raped her.
Dave (to Bret and Jemaine on the dance floor): You guys are dorking up my vibe with all the dicks. You need to spread the dicks out a little, create some lady space.
Bret: Did you use protection?
Jemaine: Yes, but only on my penis.
Jemaine: Bret. Have you seen Keitha?
Bret: She robbed us! Her and her friends jumped me, and taped me to the door.
Jemaine: Did she mention me at all?
Bret: No. Sorry man.
Jemaine: I'm not sure about her and me.
Murray (referring to Jemaine's relationship with an Australian girlfriend): And your children, what about them? What will become of them? They'll be aberrations, won't they?
Jemaine: It's pronounced "aborigines."
Dave: New Jersey, I'd love to go there but I got a lot of shit going on in the states right now.
Dave: (singing): This isn't the "Riverdance" any more.
This is a reference to the popular Irish dance troop, Riverdance, which features synchronized Irish step dancing by a large number of dancers.
Jemaine (singing): There must be fifty ways that lovers have left me.
This is a reference to the Paul Simon song, 50 Ways to Leave Your Lover, from the album, Still Crazy After All These Years (1975).
