 A way to determine the difference between time zone broadcasts of the 1997  live episode is to look at the scene with the man on the gurney who loses it  and threatens people with a scalpel. In the east coast broadcast seen by most  of the country, the scene went as scripted. In the second broadcast, the man  accidentally knocks the instruments off the table and recovered by holding  out his arms to keep the others away, still in character.
