Other mistake: When Shooter is telling Happy to meet him and the other pros at the 9th green, everyone in the background is talking among themselves, then suddenly are closer and staring at them. (00:31:47)
Other mistake: When Happy hits the ball in the alligators mouth, he is on the complete other side of the lake where the gator is located, and there is a crowd of people blocking his view, but somehow he can still see through the people and over the lake, to notice the gator taking his ball.
Other mistake: When Happy is trying to "fix" the air conditioner in his grandma's room you can clearly see there is a white board in back of the machine. When the machine falls out and hits the lady on the ground you can see it's no longer there.
Other mistake: At the begining when Happy and his dad are at the hockey game, his dad gets hit with the puck. But a second later the camera glass breaks.
Other mistake: When Happy Gilmore and Chubbs are at the miniature golf course whenever the ball comes back no one stops it or puts it back in its spot yet it is there every time.
Other mistake: When Bob Barker reaches up to grab Happy by the neck, his head is resting on the grass immediately before and after that shot. Happy was standing fully upright, so there's no way Bob Barker's arm could have been that long.
Suggested correction: Happy isn't standing. He's kneeling. You can see him stand after Bob grabs him.
