Continuity mistake: When Randy Quaid is trying to make the shot on the giant windmill, he swings and hits the ball. You can see the ball flies almost vertical and way to the right of the windmill. However the next shot shows it landing right on target.
Continuity mistake: When Ty Webb is driving the golf cart through the house, at one point he stops on a long hallway rug. You can see the rug bunch up in front of the rear tyres. In the very next shot, the rug is significantly less bunched up than before.
Continuity mistake: When Jack is attached to the machine to improve his golf swing, he takes his first shot. After he swings we see that the machine spits out another ball heading to the tee hole. It then cuts to Ty speaking then back to the machine showing it loading the same ball again to the tee hole.
