Harry Potter and the Methods of Rationality

Fred and George both laughed, as if Harry had said something funny, and bowed to him and headed back toward Gryffindor.

Harry turned back to the breakfast table and grabbed a cupcake. His stomach already felt full, but he had a feeling this morning might use a lot of calories.

As he ate his cupcake, Harry thought of the worst teacher he'd met so far, Professor Binns of History. Professor Binns was a ghost. From what Hermione had said about ghosts, it didn't seem likely that they were fully self-aware. There were no famous discoveries made by ghosts, or much of any original work, no matter who they'd been in life. Ghosts tended to have trouble remembering the current century. Hermione had said they were like accidental portraits, impressed into the surrounding matter by a burst of psychic energy accompanying a wizard's sudden death.

Harry had run into some stupid teachers during his abortive forays into standard Muggle education - his father had been a lot pickier when it came to selecting grad students as tutors, of course - but History class was the first time he'd encountered a teacher who literally wasn't sentient.

And it showed, too. Harry had given up after five minutes and started reading a textbook. When it became clear that "Professor Binns" wasn't going to object, Harry had also reached into his pouch and gotten earplugs.

Did ghosts not require a salary? Was that it? Or was it literally impossible to fire anyone in Hogwarts even if they died?

Now it seemed that Professor Snape was going about being absolutely awful to everyone who wasn't a Slytherin and it hadn't even occurred to anyone to terminate his contract.

And the Headmaster had set fire to a chicken.

"Excuse me," came a worried voice from behind him.

"I swear," Harry said without turning around, "this place is almost eight and a half percent as bad as what Dad says about Oxford."

Harry stamped down the stone corridors, looking affronted, annoyed, and infuriated all at once.

"Dungeons!" Harry hissed. "Dungeons! These are not dungeons! This is a basement! A basement!"

Some of the Ravenclaw girls gave him odd looks. The boys were all used to him by now.

It seemed that the level in which the Potions classroom was located was called the "dungeons" for no better reason than that it was below ground and slightly colder than the main castle.

In Hogwarts! In Hogwarts! Harry had been waiting his whole life and now he was still waiting and if there was anywhere on the face of the Earth that had decent dungeons it ought to be Hogwarts! Was Harry going to have to build his own castle if he wanted to see one little bottomless abyss?

A short time later they got to the actual Potions classroom and Harry cheered up considerably.

The Potions classroom had strange preserved creatures floating in huge jars on shelves that covered every centimeter of wall space between the closets. Harry had gotten far enough along in his reading now that he could actually identify some of the creatures, like the Zabriskan Fontema. Albeit the fifty-centimeter spider looked like an Acromantula but it was too small to be one. He'd tried asking Hermione, but she hadn't seemed very interested in looking anywhere near where he was pointing.

Harry was looking at a large dust ball with eyes and feet when the assassin swept into the room.

That was the first thought that crossed Harry's mind when he saw Professor Severus Snape. There was something quiet and deadly about the way the man stalked between the children's desks. His robes were unkempt, his hair spotted and greasy. There was something about him that seemed reminiscent of Lucius, although the two of them looked nothing remotely alike, and you got the impression that where Lucius would kill you with flawless elegance, this man would simply kill you.

"Sit down," said Professor Severus Snape. "Now."

Harry and a few other children who had been standing around talking to each other scrambled for desks. Harry had planned on ending up next to Hermione but somehow he found himself sitting down in the nearest empty desk next to Justin Finch-Fletchley (it was a Doubles session, Ravenclaw and Hufflepuff) which put him two desks to the left of Hermione.

Severus seated himself behind the teacher's desk, and without the slightest transition or introduction, said, "Hannah Abbott."

"Here," said Hannah in a somewhat trembling voice.

"Susan Bones."

"Present."

And so it went, no one daring to say a word in edgewise, until:

"Ah, yes. Harry Potter. Our new... celebrity."

"The celebrity is present, sir."

Half the class flinched, and some of the smarter ones suddenly looked like they wanted to run out the door while the classroom was still there.

Severus smiled in an anticipatory sort of way and called the next name on his list.
