Piss to Start

The Piss-Screen is a pressure-sensitive inlay for urinals that lets you play a game with your pee. It was designed for bars so people would take a taxi instead of driving home drunk. The game is modeled after Need for Speed so that people end up crashing if their reaction is too slow. After crashing, the game flashes the message: "Too pissed to drive? Take a Taxi instead!” Although if they really want to keep people from driving drunk, they should've invested in my idea: it's a toilet that measures your blood alcohol level, and if it's too high, a fist flies out of the wall and knocks you out. And then a midget comes by and takes your wallet. Everybody wins!
