Continuity mistake: On the last hole, Shooter McGavin overshoots the hole and the ball ends up going past the green. However once he shoots the ball off the man's foot and onto the green, we now see him coming onto the green from the fairway side at the bottom of the screen, not from behind the green past the hole.
Continuity mistake: In the final tournament, Happy's caddy puts the ball down on the green where the (fully intact) cracker is, then picks up the cracker to take a bite. When we see him up close, there is suddenly a small bite already taken out of the cracker before he bites into it.

Continuity mistake: In the scene where Shooter is with the other pro golfers, (the ones with the gold jackets) and they're drinking wine, Happy interrupts them wearing an ACDC top. Notice Shooter's wine glass switch hands a number of times, and when he tells Happy to meet them on the 9th green, the wine glass has disappeared totally.
