I happened to be in Berkeley California recently, walking down a liberal street at a fairly liberal pace, looking ahead, not at my feet. Sometimes you encounter large steel discs covering holes along the pavement and this particular plate was askew on its circular surface so that the edge formed a protruding lip. I tripped on said lip and kinda sorta almost hit the deck. In a moment of public embarrassment, I blurted out, fuckin’ manhole cover! Next thing I knew, I was cuffed and hauled into a liberal police precinct.
