Quoted from fosaisu:

Hillarious! I'm thinking either your buddy's a bachelor or that's installed on a shop-room toilet.

Quoted from littlecammi:

A friend (Rick) has had a flipper flusher like that on the commode in the bathroom next to his huge gameroom for years. He also has gun handles from some pin mounted to the wall for towel holders and a full-sized WALK/DON'T WALK crossing light (mounted high in the corner of the game room closest to the bathroom) that is wired into the light switch in the bathroom so you can tell from anywhere in the room if the bathroom is currently occupied or not. In fact, Rick's whole game room is fabulous, with multiple video arcades, four linked sit-down driver games along one wall, great pinball wall art and neon signs, a bar with sink and refrigerator, a full-sized popcorn machine and an adjacent room with more than a dozen of the best pins in top condition. I consider myself lucky to be on the e-mail list for his game parties (where I've met a lot of nice guys in the pin hobby including Lyman Sheats).
