Peter Murphy is certainly a credit to the little scavenger's tarnished reputation.
When I could not get the weasel out of my room in the morning, I left the door open to prevent the sort of damages that occurred last time he got closed into my room all day. Then I went gardening after work and wasn't home until after sundown. Thus, with my bedroom door open, he probably wandered across the keyboard sometime that evening and set the wheels in motion.
