But even he never pulled that stunt while conscious. He lost control when he was passed out - usually on a couch that we'd force him to clean.
Had a buddy like that in college as well. When he wasn't pissing himself in his sleep, he was pissing on his floor, on the wall, in the trash, on his stereo, --pretty much everywhere but the toilet! Every time he always though that he was in the bathroom.
I never set foot in his room without my shoes on --lest I step in a puddle.
