Tim: That's the most foul, cruel, and bad-tempered rodent you ever set eyes on!
Sir Robin: You tit! I soiled my armor I was so scared!
Tim: Look, that rabbit's got a vicious streak a mile wide! It's a killer!
Sir Galahad: Get stuffed!

Pretty tenuous links there.

So Wallace, Vincent and Mia are Arthur, Lancelot and Guinevere ....

OR....

pretty much any love triangle in the history of fiction?

Briefcase=holy grail is probably the best bit, but Butch as Mordred doesn't work at all and neither does Jules as Galahad. Butch is not Wallaces son (where's Morgana?) and Jules is actually older than Vincent. Also, Morderd didn't kill Lancelot, and Mordred killed Arthur, he didn't save him from rape.

King Obama: Go and tell your master that we have been charged by God with a sacred quest. If he will give us food and shelter for the night, he can join us in our quest for the Holy Nomination.
McCain Adviser: Well, I'll ask him, but I don't think he will be very keen. Uh, he's already got one, you see.
King Obama: What?
Sir Galahad: He said they've already got one!
King Arthur: Are you sure he's got one?
McCain Adviser: Oh yes, it's very nice!

SPANK ME! AND ME! AND ME!

Done.
