Sirius is having a bad day.
Looking at this now is slightly unsettling because I just realized that I gave him my eyebrows.
(Prisoner of Azkaban will always be my favorite HP book, and Sirius will always be my favorite unhinged godfather. Even though I want to punch him in the face for his general jerkiness. But I guess Azkaban pretty much punched the crap out of his face already, so never mind.)
