“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,

Dead flies and bits of fluff,
So teach us something worth knowing,
Bring us back what we've forgot,
Just do your best, we'll do the rest,
And learn until our brains all rot...”
