It's amazing how far one can get in this world on so little. SparkNotes obviates reading whole (or even parts of) books. In many shall-remain-nameless cities, driving merely requires a vehicle and an anger problem. And, if you work in the county building, a sign can rectify your peeing-on-the-floor problem.
We commend the passive aggressive janitor, or whoever wrote this, for speaking mostly in the positive, "Please use urinal" as opposed to the negative: "Don't pee on the floor." We also commend bathroomgoers there for apparently not yet peeing on the sign.
We can't make it out, but we imagine the smaller text below reads: "asshole."
Thanks to Gary for this image.
