One day I bought a very expensive mobile phone...all of a sudden I wanted to the toilet...then I sat and my phone just dropped into endless hole!!!!!!!!!!
That must have been really depressing unless you are a cripple or handicapped? Was the grandma a body builder or some thing?
I did that once with my xbox controller, only I knocked it into the toilet after I was done. I grabbed it as fast as I could and wiped it off. It still works just fine but I make other people use that one.
I guess the worst 15 minutes of my life were during a violent situation at home. Nothing is scarier than not knowing if you'll see your family alive if you even walk out alive. :S
Multiple car crashes, coach crash, hit by a car as a pedestrian, broken leg from a fall but didn't realise till a few days later when the bone ends moved and ground against each other (just thought I had a badly bruised leg), free-diving in a river and misjudged the ascent time (heh)... ah, it goes on and on...
