Back in my sportier days, I always held complete contempt for those who lacked all athletic ability, but still went through the motions of working out. While a bit irrational, it fell into the same sort of Darwinian category as my hypothetical fear of falling in love with a previously hideous individual who'd secretly undergone grave plastic surgery, only to be discovered when looking into faces of my children. Muscles, in my mind, were meant for jocks. Letterman's sweaters, however, when old enough, are classic fun, even if you can't throw a ball or a punch. Bids for this one hover at $36.
