Yeah when I was a kid I was playing with a friend on one of those spinny-things (I can't remember what they are called, the ones you push on to spin and they go faster and faster the more you spin them) and I was lying down on it and he thought it'd be funny to jump in front of me and scare me. Only problem was when he did it I got about a pint of sand lodged behind my eyeball. I remember how badly I freaked out trying to get the stuff out, it felt so fucking WRONG.
