Subway rings to prevent mistaken identity

It seems that the issue of women being groped on the subway is old hat, but there are these subway rings that are currently on sale for men who don’t want to be mistaken for a pervert. Whenever you’re on one of those extremely crowded trains, just place your hands in one of these rings so you won’t be thought off badly by a mistaken lady. Amazingly enough, this product was sold out almost immediately when it was put up for sale, which goes to show just how many innocent men want to uphold their reputation. When will they build in MP3 playback functionality as well as Bluetooth connectivity into one of these?
