It turns out Shepherd got the local golf pro to manufacture a fitting for the head of a 6-iron to connect on to the end of the handle they normally use for collecting moon rocks. After a small argument with his NASA bosses he was given permission to take it with him, connected it to the collapsible handle during a moon walk, and played golf on the moon.
Alan Shepard: (Facing the TV) Houston, while you’re looking that up, you might recognize what I have in my hand as the handle for the contingency sample return; it just so happens to have a genuine six iron on the bottom of it. In my left hand, I have a little white pellet that’s familiar to millions of Americans. I’ll drop it down. Unfortunately, the suit is so stiff, I can’t do this with two hands, but I’m going to try a little sand-trap shot here. (Pause)
