Snape: Damn it, Quirell! I got you the good stuff! Now where's my money!?
Quirell: Uh, I'll have it for you soon!
Snape: I got you front row tickets to that Hannah Montana concert!
Quirell: I'll have it tomorrow!
Snape: *Sniffs the air* Something smells like shit...
Quirell: Must be Potter!
Snape: *Reaches out hand* Nothing there...
Snape: Oh wait, *sniffs the air, again* it's me...
