critics are mudflaps...

..and i'm not sure exactly how it works but i thought of the idea as i was walking, on my way to work and i saw a mudflap that was detached from the truck and it was sitting there on the sidewalk and although once part of the truck it is now separated and it serves no function and it is strange that it was on the sidewalk but then it made sense because the sidewalk was actually below an overpass and it easily could have fallen from the truck, over the railing and onto the sidewalk. that doesn't answer any questions though, does it?
