The Hogwarts Sorting Hat

"Oh you may not think I'm pretty, but don't judge on what you see, I'll eat myself if you can find a smarter hat than me. There's nothing hidden in your head The Sorting Hat can't see, So try me on and I will tell you Where you ought to be.

And now the Sorting Hat is here and you all know the score: I sort you into Houses because that is what I'm for. So put me on! Don't be afraid! And don't get in a flap! You're in safe hands (though I have none) For I'm a Thinking Cap!
