“Harry, Cedric, I suggest you both go up to bed," said Dumbledore, smiling at both of them. "I am sure Gryffindor and Hufflepuff are waiting to celebrate with you, and it would be a shame to deprive them of this excellent excuse to make a great deal of mess and noise.”

“Oh, very good,' interrupted Snape, his lip curling. 'Yes, it is easy to see that nearly six years of magical education have not been wasted on you, Potter. 'Ghosts are transparent.”

“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.
You can keep your bowlers black,
Your tops hats sleek and tall,
For I'm the Hogwarts Sorting Hat
And I can cap them all.
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.
Y ou might belong in Gryffindor,
Where dwell brave of heart,
Their daring, nerve, and chivalry
Set Gryffindors apart;
You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true
And unafraid of toil;
Or yet wise old Ravenclaw,
If you've a ready mind,
Where those of wit and learning,
Will always find their kind;
Or perhaps in Slytherin
You'll make your real friends,
Those cunning folk use any means
To achive their ends.
So put me on! Don't be afraid!
And you won't get in a flap!
You're safe in my hands(though I have none)
For I'm a Thinking Cap!!”

“But Dumbledore says he doesn't care what they do as long as they don't take him off the Chocolate Frog cards.”
