Well...
I had this idea for a machine that could be installed in men's restrooms. See, imagine your standard urinal, but turn it into a video game: you've got the bad guys running around on the screen, and when you pee on them you're killing them dead. It'd be like an arcade shooter, but you'd have to drink lots and lots of water while playing.
I'd called it "Pissed Off 2: The Peevenge"
So, if THAT was installed, I'd be pissing on a lot of very upset digital bad guys.
