Remus: Okay…. Lets go over this one more time… If you bite it and you die, it’s poisonous. If it bites you and you die, it’s venomous. Got it?
James: I think so….
Sirius: Wait, I have questions! What if I bite it and it dies?
Remus: That means you’re poisonous.
Sirius: And what if it bites itself and I die?
Remus: That’s voodoo.
Sirius: Okay, but What it is bites me and someone else dies?
Remus: [getting annoyed] That’s correlation, not causation.
Sirius: Alright, and What if we bite each other and neither of us die?
Remus: That’s…. kinky?
