It dawned on me while I was at work today. It's many times more entertaining to pee in the toilet bowl rather than the urinal in the men's room... for guys at least.. or at least this guy.... uh huh... so aside from the resonating melodious musical tinkle, you can also draw pictures with the bubbles. With the musical tinkle, you get different pitches according to the depth of the water. The bathroom can be a room of spontaneous creativity.
