I'd like to know a bit more on the concept of the knee test, who first came up with the idea? Where was it first tried? What this done in public or in front of aspeech committee? How many people who took seriously of this short had actually tried the knee test, and finally how long was the fad around. I imagine many people saw this since it was made by Centron and Centron seems to have made about 3.5 million short films (was Carnival of Souls a Centron Production?)I was also impressed with Herk Harvey's combing hair and tie tying abilities, pure genius. But the big question remains, How good a speaker was Mr. Harvey? Since he no longer lingers on this planet we must find out from others who are still alive and have been graced with the presence of Mr. Harvey. Surely some survivors of the Centron years must still be alive and maybe not have Altzheimers. These are things that must be answered!!!! BTW: The short was still quite goofy!!
