Why Snape Doesn't Teach DADA
---
"Silence, everyone, if you please. Now. Pay close attention. Boggarts can be dangerous creatures if not properly handled." So saying, Snape went on to explain--in the most solemn manner imaginable--that one fought a Boggart by thinking of something that rendered it amusing, and shouting, "Riddikulus!"
He then proceeded to demonstrate by loosing the Boggart from the wardrobe. Luckily, none of his students had ever seen a young, clean-shaven Sirius Black.
"Riddikulus!"
Black now dangled from a gallows, tongue protruding grotesquely, eyes bulging out of his head.
"Very well, now you dunderheads give it a try. Longbottom, you first."
