Singing Wet Floor Sign

Wet floor signs may be helpful, but they are also fairly easy to miss. If you aren't paying too much attention to where you are going, then the next thing you know, you'll be on the floor. And what about blind people? They really don't stand a chance around wet floors. The singing wet floor sign would solve this. It would be better if it didn't play a proper song, in case people mistook it for a radio or other background music. A simple ditty would suffice. It may sound strange, but how many people here honestly don't automatically think of ice cream when they hear the ice cream van's song?

Of course, 10 years after being introduced, a cheesy disco band would release a cover version of this, spend 3 weeks at the top of the charts and then fade into obscurity never to be heard of again.
