I'm Professor Snape
Don't get in my way
If you try to fool me there'll be hell to pay

Neville is a dolt
Weasley is a geek
Granger is a know-it-all who loves to speak

Potter's always sneaking somewhere
Thinks he's quite above the rules
He's just like his father
I'd rather not be stuck with all these fools

My hair and eyes are black
So are all my clothes
If you want to stay alive don't talk about my nose

Hogwarts is my school
Potions is my class
Those who try to cheat will always wind up on their ass!

Better keep your cauldron boiling
Never know what's next in store
Nothing here is easy
So my hair is greasy-
But I've never ever been a bore
