Welcome to Hogwarts

Hogwarts, Hogwarts, Hoggy Warty Hogwarts
Teach us something please
Whether we be old and bald
Or young with scabby knees
Our heads could do with filling
With some interesting stuff
For now they’re bare and full of air
Dead flies and bits of fluff
So teach us things worth knowing
Bring back what we’ve forgot
Just do your best, we’ll do the rest
And learn until our brains all rot
