I'm sure it sounds like sh$# 
 
Not a very original idea anymore, Dick Dale had one of those way back when. There was also a company called "Royal Flush" that tried to market toilet seat guitars in the 80's. Still, a cool find. 
I made one myself for a punk band about 15 years ago. It was mostly just a stage prop so it's just a plank with a piece of wood for a bridge, but it was playable.
