The Man with a Face

There's a man with a face on the back of his head
He did whatever the head-face said.
He wore a large turban to cover his plight
For the face on his head was a gruesome sight.

He was a professor at old Hogwarts,
But the job was cursed, and so he was forced
To travel the world after just one year,
And when he returned he was filled with fear.

He never did say what horrors he faced,
But when he came back, his hair had been replaced
With a pasty, writhing, evil mug
That survived by drinking unicorn blood.

There's a man with a face on the back of his head
He did whatever the head-face said.
He wore a large turban to cover his plight
For the face on his head was a gruesome sight.
