This is a Harry Potter special.
NK calls me up.
NK: Why did Snape stand in the middle of the road?
Me: Eh? I dunno…
NK: So that no one would know which side he’s on!
NK: Want another one?
NK: Why did Barty Crouch stop drinking the Polyjuice Potion?
NK: Because he was becoming Moody!
Me: Oh god, why?
