When I read this, my first thought was the old Simpsons episode when Ned Flanders and Marge are in a play (I think it was a musical version of A Streetcar Named Desire). Ned takes off his shirt, and he is ripped with a body that would make Chuck Norris blush.
Of course, I think Marge ends up imagining something bad Homer did to "get into character", flips out, and beats up Ned. Although that may not be an indication of his lesser strength, but his moral character that prevents him from fighting back.
Not that it proves anything; but then, I question whether the study in the article proved anything, either...
