I don't remember if anyone asked this one before...did they ever have an accident with one of those giant lighted cards that slides over to "cover" the front game (the ones the contestant stands in front of during the Money Cards)? In the early episodes (somewhere up into the middle of the Raffety run) they had the cards tilt for an added effect but stopped doing that before the Rafferty episodes ended. It always seemed like they had a heck of a time getting them to tilt and whenever they uprighted them, it looked like they came down with a hard thud.
Makes me wonder if one of them fell over at some point (or close to it) and they decided the added effect was too much of a hazard to risk.
