Sirius and the never ending closet

Sirius has a closet, but he has no idea how much clothing he's got in there. So the Marauders decide to go in there to see how big it is. Moony gets lost. Wormtail gets buried under stacks of leather jackets. Prongs keeps telling them that he was sure he saw a dementor somewhere and Sirius tries to tell him that it's only an old cloak.
