When I got out of the shower this morning (sorry about that mental image) I heard thumping. I assumed cat shenanigans and continued to dry off but then I noticed that the thumping seemed to be coming from the roof. This still didn't phase me. Sometimes the cats can be tricky. Outside the powder room window, however, I heard the distinct sound of quacking. Although I saw no duck-related evidence later in the day, I must conclude that there was a duck hanging out on my roof.
It was either that or a monkey with a duck call.
