Chapter 1
Remus had documented when all the staircases in Hogwarts moved throughout the day. When Sirius had particularly annoyed him one day, Remus led them to a staircase about to move, pushed Sirius down it as it moved and sent him tumbling like a bowling ball into a group of Slytherin first years who fell like dominos. When Sirius looked back up Remus was doubled over in laughter, clutching at his sides with tears streaming down his face.
A day in the hospital wing with a sprained wrist for Sirius and a pulled muscle for Remus was well worth it for the hilarious stories they told for the next two months. Also the hesitancy with which the Slytherin first years moved around the castle now, like they were waiting for Sirius Black to come rolling towards them.
