Was in a long, long series of classes for some Government work eons ago. One day, without any notice, a man bursts into the room, pretends to shoot the instructor (blanks) and runs out a side door. It was amazing the varied descriptions given of the man by the class members, who had been handpicked for this job. Plus, no one could remember what the intruder said during the brief episode or if he had said anything.

And, what Jeri said.
