The worst idea I've ever had

The plan was simple: borrow a joke book, enchant one suit of armor, and return everything before the curfew. What actually happened was the armor woke up the portraits, the portraits woke up Peeves, Peeves found the fireworks, and now half of Hogwarts thinks a secret rebellion is taking place. The good news is that nobody knows it was me. The bad news is that the Marauder's Map is currently lying on the floor with my name glowing right in the middle of it.
