I do love that movie, however this shot in the dark was Dr Dahl taking a needle to both of my knees. First was the Lanocane, then drawing the fluid out of my knees (the right one had blood in it), and the last step was putting in Cortisone.
I decided before we go west, I would give this a shot (oh a pun to my double entendre). How was it in the dark. Well I closed my eyes when the Doc put the needle in, hence it was dark. I don't mind the insertion, but I don't like to see it. I guess it is unfounded fear, but it works for me. Once the needle was in I could open my eyes.
