Harry Potter and the Philosopher's Song

To the melody of "The Philosopher's Song", by Monty Python

Albus Dumbledore was a frightfull bore who was very rarely stable,
Severus Snape was a drunken ape who could drink you under the table
Madame Hooch prefers them huge
buys drinks from every quid
And McGonagall was a drunken brall who was just as schlossed as Hagrid...
There nothing Flitzwick couldn't teach you about the levitating of the wrist...
Voldemort himself was permanently pissed...
