Here are a series of signs, most with well intentioned instructions or messages, that have been vandalized with sarcastic responses. Everyone at some point has probably felt the urge to stop, look in all directions to make certain no one is around, and pull out the pen (or in one of these pictures, what looks to be trading-card style stickers of famous rappers) to do what has been done here. However, the vast majority of us do not act on these urges. Instead, we leave it the brave few among us to entertain - or enrage, if you were the one that took the time to create these signs - the rest.
