When Rob Lowe is hitting golf balls into the canyon, his golf club switches from a righty to a lefty and then back, plus his swing side also switches. At the end you see him line up as a lefty, but then the long shot shows him hitting as a righty. This must be a post edit horizontal flip as Jack's jacket also magically flips from a button up left to a button up right jacket. Jacks hands are in his pockets in the back shot, but in the fore shot, his hands are out of his pockets.
