i just think you haven't had pooh problems. that shit sounds pretty real to me. i've been at parties where similar has happened (gotta love hanging out with mostly guys i guess). once one guy was in the bathroom dropping a load, and another drunk guy was going to puke, and he couldn't wait so he opened the bathroom door and ended up yakkin in the poopin guy's lap. spaghetti. i almost pissed myself laughing at them.
and one of my gf's bfs was notorious for killing toilets. i refused to go in public with him after awhile, it was so bad. it took one time at a place with a general use bathroom (no mens/womens) and me going after him to realize exactly why he always came out of a bathroom grinning like an idiot. there was a log bigger than my thigh floating on top of an overflowing toilet, and it was overripe, if you know what i mean.
oh and another, another gf's brother was lactose intolerant, drunk, and had just killed an extra cheese pizza. so he's at our place (she and i were roomies) and he's on the toilet and hugging a trashcan. after about 40 minutes of that going on down the hallway, i shut my door. it was late, i was just dozing off when i hear screaming (his). MY LEGS MY LEGS OH GOD MY LEGS and he starts sobbing. gf runs to the bathroom to see wtf was going on - it is 3hrs since anyone checked on him. he passed out while sitting on the toilet, fell over, woke up and couldn't feel his legs coz they had fallen asleep. he's laying in a pile of puke and his shit ass is hanging out. i let his sister handle that one too.
i coulda written those better if a) they'd happened directly to me and b) i spent some time but it don't c) make the stories any less true.
