This is the Complete and Total Loser's father, circa 1971, throwing a basketball. He would be 51. Never a very active man even by the standards of the day, it's a rare picture of him. The Loser took the photo out of a photo album to scan and send to his brothers, as he did a different last year on this date, his late father's birthday and saw written on the back, in his aunt's loopy flair-pen handwriting, "Wish I was this graceful too!"
Well put, Aunt Bea.
