I Did Too

I used one with 6 friends on a weekend away 4 years ago, we`kept asking questions all we` could get it to spell out was "Yellow car" over and over maybe 10 or 12` times gave up eventually and decided one of us was doing it (no one owned up) 4 days later my brother was knocked off his bike ,he was injured but not too seriously, the driver swerved and hit a parked car. .He was really angry and told us he had` just had`it repainted a few days ago, it used to be yellow..could have been a coincidence...I dont know
