Hogwarts

Hogwarts
Hogwarts, Hogwarts
hoggy warty Hogwarts
Teach us something please
Whether we be old and bald
Or young with scabby knees,
Or 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
And learn until our brains all rot
