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.

Revealing: In the scene where the volkswagon is driving on the golf course to run over Happy, you can see tracks in the ground where the car had already been.

Revealing: When Happy tosses the IRS agent out of Grandma Gilmore's window, he falls down the steps outside and it is blatantly obvious that he is wearing kneepads under his suit pants.

Continuity: When Happy pleads with Chubbs to take him for lessons, he shakes Chubbs' hand. He pulls off a few fingers, but not his ring finger. When the shot changes to behind Chubbs, you can see that his ring finger is not there.

Other: During the last tournament scene at the beginning of it look at the Media Tower the crashed V.W. is already there but that part has not happened yet.

Continuity: The point in the movie when Shooter is mad about the beach ball being thrown on the green, watch his ball. It changes it's position on the green from one view to another.

Continuity: When Happy is about to putt and the tower starts to fall, his caddy is behind him. In the next wide-angle shot, his caddy is in front of him, or at least between Happy and the hole, where before Happy was between him and the hole. A couple of shots later, when Virginia runs up to Happy, the caddy is back to his old position again.

Revealing: When Happy and Bob are rolling down the hill, you can see from the face that it's Bob Barker's stunt double.

Plot hole: If Happy has enough money to bid on his Grandmother's house then he has enough money to pay the back taxes to the IRS and stop the auction. Also, the IRS only cares about the taxes, anything bid over the tax amount is returned to the owner. Happy could bid a million dollars and win, at which point he'd have to pay his own Grandmother, something we can probably assume she wouldn't sue him for, given their relationship.

Continuity: Happy and his new caddy are discussing the shape of the green and the caddy says the green is slanted to the left. When Happy tells him it only seems that way because he's missing a shoe, the caddy is standing with his feet shoulder-width apart. When the camera cuts to the close-up of his feet, they're together, yet the caddy didn't move.

Continuity: In the beginning when Happy first meets Chubbs, Happy backs his car into a couple of trash cans after Chubbs mentions big bucks. When Happy backs into the trash cans and stops he leans out the open window with his elbow over the side; you can see this through the back window. But when it shows a close up of Happy in the next shot, he's sitting calmly in the car with both arms in his lap.

Continuity: When Virgina hits the puck during the skating scene, the puck can be seen going in that blue area in front of the net. In the next shot, however, the puck is only halfway towards the net.
