When I was in my late teens/early 20's, my dude was a fuckin alcoholic who would pass out and pee the bed. It was the nastiest, grossest thing I ever went through in my life.
I had a cousin who would get drunk and piss in chairs, thinkin they were the toilet.
I can't think of a time I ever pee'd the bed, but I, too, have had the 'hang you head out of bed and hurl' thing happen a time or two.
