The entertainment is almost entirely from the interviewees, all of whom were very good-natured about their do's. Several had great senses of humor. I really only saw one case where anyone was "stalked". In the opening minutes, the producer pursued a man down the street in NYC, backing off when the guy threatened him with bodily harm.
There were two big surprises (not at all spoilers). One was the young man who deliberately shaves his head so that he can have a combover. I'd say the best word to describe him would be "individualist", or perhaps "eccentric" (in a positive way).
The other was the son of the man who actually patented the combover. I never would have guessed such a thing could even be patented. Judging from the man's home, it doesn't appear to have been the most lucrative patent one could hold.
If you get a chance, don't pass this one up!
