Michael Henry has other little ditties, like "Wow, You Have a Beard". Avoir, to have, is what make you valuable? Here, it seems that chest hair is an optional extension of the beard -- except that not everybody can have it.
In reviewing a different (only distantly relevant) film, I happened to look at his imdb again, and don't see mention of Everglades now, but instead this filmography, which is interesting in its own way. (See that day.)
