Had a new one last week - a guy at a stop light yelled at me out the passenger window of his car "bicycles can go on a red light". His passenger translated that for me as I could not understand what he was saying. My reply was "Thanks, but I don't think the other cars at this light would agree with you.".

The guy was not nasty or anything. He actually had good intentions (unless he intended to run me down when the road went to a single lane a 100 yards up from us!).
