Reality Checkpoint

Reality Checkpoint is the humorous nickname of a large cast-iron lamppost in the middle of Parker's Piece, Cambridge, England, at the intersection of the park's diagonal paths. It gained the nickname in the early 1970s when it first appeared on the lamppost's base as graffiti, possibly by a student. The graffiti was sometimes removed by the local council, but soon reinstated. The nickname is now officially painted on.
