There are quite a few mad scientists in my men's social club, and a few of them actually proved spider strength's superiority to bald guy's strength scientifically. They irradiated me and then had me bite a puny high school nerd.
Did the kid gain the proportional strength of a bald guy? The results were inconclusive, as my strength is pretty much the equivalent of your average puny high school nerd. But the test subject's hair did get a bit thinner within the week, and I had to have some skin abnormalities removed a few months later.
