Bilbo Baggins: [Bilbo interrupts as he's about to eat Gloin] Uh... not... not that one, he... he's infected!
William Troll: You what?
Bilbo Baggins: Yeah he's got worms in his... tubes.
Tom Troll: Ooh!
[Tom throws down Gloin 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!
[to Bilbo]
Kili: You have parasites!
[Thorin realizes that Bilbo is trying to buy them time and kicks Kili and they 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!
