And the school bellowed: 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 are bare and full of air, Dead flies and bits of fluff, So teach us things worth knowing, Bring back what we have forgot, just do your best, we will do the rest, And learn until our brains all rot.
