I liked the comment from the woman in the beige coat:"I'm invisible - not bad!" - Did you hear the audience clap? They'd appreciated the "other" way this woman/we, has to view the World. She was in awe, while the others saw this as a "fault"?
It was this whole way, us as humans, attempt to readjust our "reality" into what is the reality that confronts/apprehends us at a any given moment in our day, that got to me. So on one level, yes, it was humorous, but on another level deeply fascinating too.
Modern "equivalents" like "Punk'd" tend to be mean-spirited and go for humiliation, whereas in the old CC, even the "victims" almost always found the setups very funny, and were never subjected to humiliation.
