Who is the cruellest magician?

One guess that's who?

Who is that stranger with a great big nose?

Who dresses in black from head to toe?

Who's always wrong, and never right?

(Yeah?)

Who'd ever dream of starting a fight?

(That's who?)

Who looks like a Darwinian ape?

No one!

(WACK! WACK! WACK! WACK! WACK!)

But Professor Snape!

(Yeah!)
