Taking a more purists standpoint when dealing with Kevin Bacon Greased Lightnin' contact enhancers, the shorter signal path, the better. For avoiding noise and degradation reducing the number of parts the signal goes through and thus minimize the length of the path from input to output, it's best to loose your Fruit of The Loom boxers, or briefs entirely and just go full out commando Bare Wire. I did just hear through the grapevine that the new fad mod for the Strange Fruit System Suspension Swing is no longer the plastic oranges and wax apples, but all about the Ginkgo Biloba rubber grapes. This odd question you ponder about, as far as what underwear Fabio wears? If I had to take a wild guess, I would think that it's safe to assume that Fabio may be a DK design by Donna Karen Edible Undies wearer?
