Crosswalk distrust

[Gregory]

The irrational suspicion held by every human that tells us we cannot hit a [crosswalk] button just once. Our intuition tells us that, if we only hit [the button] one time, the electronic signal will not be sent sufficiently to the traffic light. Therefore, every pedestrian makes a fist and hits the button -- rapid-fire style -- until [lactic acid] causes our triceps to cramp up and shut down.
