William Kircher: Bifur, Tom Troll
Bilbo Baggins : [Bilbo interrupts as Tom the troll about to eat Bombur] Uh... no, no, not... not that one, he... he's infected!
William Troll : [taken aback] You what?
Bilbo Baggins : Yes, he's got worms in his... tubes.
Tom Troll : Ooh!
[Tom throws down Bombur in disgust]
Bilbo Baggins : In-in fact, they all have. They're infested with parasites, it's a terrible business, I wouldn't risk it, I really wouldn't.
Oin : Parasites? Did he say parasites?
Kili : Yeah, we don't have parasites!
Kili : You have parasites!
[Thorin realizes that Bilbo is trying to buy them time and kicks Kili, and the dwarves realize what Bilbo is doing]
Oin : I've got parasites as big as my arm!
Kili : Mine are the biggest parasites, I've got huge parasites!
Nori : We're riddled!
Ori : Yes, I'm riddled!
Dori : Yes, we are, badly!
