Continuity: When Happy is trying out for the hockey team, he sends a slapshot in front of the coaches and it breaks the glass. In the next shot the glass is intact.

Revealing: In at least one scene, you can see the ruts that the filmmakers made in the greens to make Happy's putts go where they wanted them to.

Plot hole: In the final tournament when Happy is stuck in the rough, he swings five times. Assuming he hit his drive into the rough and hit an AMAZING shot from the edge of the water into the hole, he still could do no better than a seven on the hole. Happy only lost one stroke on the hole.

Continuity: The exact same shots of the golf ball sailing through the air are used two or three times, especially during the last golf tournament.
