Well.....
Drunk one night, many years ago, returned to a friends house. I stumble into the bathroom in the dark. His parents, possesing of superior interior decorating skills, had one of those fluffy carpeted toilet seats. I'm sure you can all tell where this is going, but lets just say that a stream of urine landing onto the surface of one of these soaks in and sounds exactly like a stream hitting the water in the bottom of the pan. Naturally I denyed all knowledge and didn't get invited back. I say it was an honest mistake.
