Severus Snape hated Potter
He loathed Harry's late father James
He didn't like Dumbledore's scheming
Or Voldemort's sly little games
He'd always despised Remus Lupin
And Sirius Black he'd abhorred
That Pettigrew boy he'd have pitied
Had he not made friends with the Dark Lord
He disliked the Weasleys and Malfoys
He thought Fudge a pompous old fool
He scorned all the children he met with
No wonder he taught at a school!
