Walking Signals

I've had this one in the queue for a few weeks, but finally, this morning, I found the missing piece. I sort of knew what to put in the first three panels, but once I thought of the final panel, the cartoon was ready. The next thought was how to package it. Since I am not a cartoonist, I needed to format the discussion so that two guys in the office could make all the points. That meant it had to be another person who was actually punched by a turn signal. Of course, it also requires that you remember your hand turn signals.
