Sometime in the Fifth year . . .

For some reason the new Defense Against the Dark Arts teacher really hates Snape. He decides that if he's better at Defense Against the Dark Arts than him, that he's also better at Potions than him. So, he makes something, and slips it into Snape's drink sometime in the staff room where the teachers are having a meeting of some sort.

As soon as Snape drinks it, he realizes that there's something wrong with it.

"Has someone poisoned our drinks?" he wonders aloud.

The anal Defense Against the Dark Arts teacher, we'll call him Professor Bob at the moment, stands up and shouts, "Ha! I've put a special potion in your drink! Can you tell me what it is, Mister Potions Master?"

Unfortunately, Sanpe can't. Furious, he leaves the room.

"What did you put in the drink?" Dumbledore asks, and Professor Bob laughs.

"Just you wait until tomorrow morning . . ."

Next morning, Snape does not come down to breakfast. He misses all his classes that day, and Dumbledore and the teachers are a bit worried, so they go to his office, to his room, and knock loudly on the door.

There are students with them also, wondering what has happened to the Potions Master. Most likely, Harry, Hermione and Ron are there as well.

"Severus, are you alright?" Dumbledore asks gently through the door.

An unusually high voice answers, "I'm fine! Leave me alone!"

"I'm sorry for what ever Professor Bob did to you," Dumbledore says. "Can you please open the door?"

"No . . . I - I can't!"

"Why?" Dumbledore persists. "Did you look bad?"

"No - I look wonderful."

Dumbledore and the students and teachers with him are confused.

"Wonderful?" Dumbledore asks. "What do you mean by that?"

The door creaks open as Severus goes on to say, "This Wonderful."

And here's the wonderfully funny mental image: Snape coming out of the door as a WOMAN. He, hee . . . don't know where that one came from.
