Since wearing the Vibrating Underwear is designed to "secretely get off in front of people" I would have my wife wear them to a college football game and let her experience getting off in front of 75,000 people. Walking around the stadium and tailgating before the game would be just a teaser until we enter the stadium and them the magic would begin if she could wait that long. Did I mention she would also be wearing a short mini skirt? Hopefully she wouldn't get too wet to have everyone notice her juices dripping down her legs.
