This summer I discovered the most amazing thing, my bathroom is acoustically perfect. The walls are about 15" thick and the bathroom is about 9' sq ft., and if the door is closed the room is a perfect square. These leaves it isolated from all other disturbances in the house. This means that when you pee, it's like hearing yourself pee in surround sound stereo. It's the most awesome thing in the world. After the demonstration of this to my friends, CthulhuFhtagn, or Adam, hauled my guitar up into the bathroom. We shut the door, and he played in stero sound, it was awesome.
