Another funny thing that happened to me was with my wiper washers. Use to own a Civic and to turn the front wipers on you twist the lever. Well twisting the lever on the OBS turns on the rear wiper, if you twist and hold washer fluid squirts out.
So here I am driving down the road squirting washer fluid on my rear window and my front wipers on trying frantically to turn them both off. Lucky I didn't get into an accident.
