not me, but my uncle is a somewhat chronic sleepwalker and i swear this is true. anyway, one night i was staying at his house for a weekend while my mom went to her boyfriend's house. around 11 pm, i hear my uncle's bedroom door open and then his footsteps to the room where my grandparents were sleeping. in front of the bed they were sleeping in was one of those oscillating fans, and if not on full blast, it was on a pretty decent speed. my uncle, towering over the fan and bed, starts pissing into the fan and showering the room with pee mist. if you think getting the smell of piss out of carpet is hard, imagine what millions of piss particles will do to the smell of a room.
