The song is by pink and the characters are JKR's
Enjoy!
Don't let me get mean!
I teach potions
Slytherins my team
My clothes are always black
And my socks are always green
Hermione dated me
My parents hated me
Potters always in a fight
Neville can't do nothing right
Everyday I fight a war against the students
Can't take the insults thrown back at me
I'm a hazard to Potter
Don't make me get mean
I'm your worst enemy
It's bad when you mess with my head
So irritating
Don't want to teach potions no more
I wanna teach dark arts instead
Albus told me
You'll be a turncoat
All you have to do
Is serve Voldemort
Tired of being compared
To damn Lucius
He's so evil
Just like a weasel
I'm a hazard to Potter
Don't make me get mean
I'm your worst enemy
It's bad when you mess with my head
So irritating
Don't want to teach potions no more
I wanna teach dark arts instead
