Continuity: Coach Brakett (Boyd Gaines) finally convinces the young gym teacher, Honeywell (Kim Cattrall), to go with him to the boys' locker room. Once they are up there he disrobes her and gets on top of her. When they cut to a close-up, you can tell that he has longer hair than just two seconds before.

Continuity: When Brian Schwartz drives away in his sports car, you can hear him shift 4 times. When they show a shot of his car go by, he is only going about 5 miles per hour.

Continuity: At the end of the film we see Sheriff Wallace shoot the hood ornament from Porky's car. A moment later we see Porky and his gang pushing the car away and the hood ornament is back on.

Continuity: At the end of Porky's, you see Mickey Jarvis on crutches and covered in bandages after getting beaten up by Porky. In the beginning of Porky's 2: The Next Day, Mickey has miraculously healed. He jumps out of his truck to catch up with the other guys, no crutches or bandages and he is walking fine.

Continuity: When they guys are fleeing the house in the woods, in the long shot Meat is in front of Mickey, but in the close up Mickey is in front of Meat.

Continuity: When Timmy cleans out his gym locker, he took only two items from the locker, stuffing them in the basket haphazardly. In the next shot when he is at the counter returning them to the phys ed coach, the basket is now full of at least six different items, all neatly folded.

Continuity: When Porky pulls the lever we see the guys fall into the river. Then from another shot we see them get out, and go round to argue with Porky, but they are now dry. Impossible considering the few seconds time difference.
