Actually I shoulden't joke. My Great Aunt died of a heart attack on the bathroom floor (1986/ she was in her late 80's and very overweight), We figure she used one of those pressure cans to clear a blocked line in the kitchen sink (we found it on the counter), but it ended up "barfing" all the......errrr.....stuff back out the toilet in her bathroom. The bathroom walls were covered with black stuff that had exploded out of the toilet. When she opened the door we figure the shock of seeing what had happened caused a massive heart attack.
She was found on the floor of the bathroom, curled up in a ball.
