From "Monty Python and the Holy Grail"
RIGHT HEAD: Oh, cut your own head off!
MIDDLE HEAD: Yes, do us all a favour!
LEFT HEAD: What?
RIGHT HEAD: Yapping on all the time.
MIDDLE HEAD: You're lucky, you're not next to him.
LEFT HEAD: What do you mean?
MIDDLE HEAD: You snore.
LEFT HEAD: Oh I don't -- anyway, you've got bad breath.
MIDDLE HEAD: Well its only because you don't brush my teeth.
RIGHT HEAD: Oh stop bitching and let's go have tea.
LEFT HEAD: All right all right all right we'll kill him first and then have tea
MIDDLE HEAD: Yes.
RIGHT HEAD: Oh, but not biscuits.
LEFT HEAD: All right all right not biscuits, but lets kill him anyway.
ALL HEADS: Right!
