I noticed this cardboard sign dangling from a stop sign near our office and stopped to read the strange notices scrawled on its front and back. I assumed it must be part of IFC series Portlandia, which was shooting in our office yesterday. But when I asked the crew if they knew anything about it, they shook their heads.

I have few clues to understand this mystery sign. The sign was hung on a stop sign with no bike around at all. Ideas, anyone? My theory is: bike was chained to pole for a long time, infuriating neighbor who made funny, passive-aggressive notice, bike owner's mom removed bike, writing back aggressive-aggressive notice.
