Corrected entry: In the short scene where Bobby is standing in front of his class holding a large molecule, the diagram of the molecule can be seen on the blackboard. In part of this diagram a carbon atom 'C' can be seen bonded to five other atoms. As all good chemists know however, carbon can only form four bonds and so this molecule could not possibly exist.
Corrected entry: When the Muddogs are playing the Iowa Hawkeyes, just before Bobby blocks the field goal, the offensive lineman on the left doesn't move at all when the center snaps the ball.
Corrected entry: When Bobby rings up Captian Insano, the man with the host in the black suit says, "It's our (old) friend from Jackson's Bayou." When he says that, he's obviously saying that Bobby rings more often. Then how come they start laughing at him if they know him? And Captian Insano must have heard him already on the show, so why did he say he was 11 or 12?
Corrected entry: In the final game, the opposing team's coach sends in his best defensive player, "Meanie", to try and pound the ball at the Waterboy. However when Meanie runs out onto the field, the offense has already broken the huddle and lined up. This would be a penalty for an illegal substitution in college football. However no penalty is called and Meanie runs out way after the huddle is broken making this penalty entirely too obvious to miss.
Corrected entry: Bobby's shoulder-pads alternate between being very high in close-ups and normal when he is on the field.
Corrected entry: Throughout every game and practice in the movie, Bobby Bouchet is not wearing a mouthpiece. You're suppose to have a mouthpiece in while practicing or playing, for many reasons, such as: teeth protection, concussion prevention, etc. Bobby plays linebacker, if anybody should be wearing a mouthpiece, it's him.
Corrected entry: After Bobby passes his equivalency exam, he says to Vicky "we better get going, I told Coach Klein I would drive to the game with them". The game however, doesn't take place until the next day, as we can see Bobby spends the night in the hospital with his mom then plays the next morning.
Corrected entry: When coach Klein is watching the game footage before bobby's interview for waterboy, the opposition intercepts in the game film, runs it and drops it, but then simply picks it up and runs for a touchdown. Klein jokes about how much time he had to pick it up and keep going, but that would be a fumble and the play would be at that moment be dead.
Corrected entry: When Bobby, Vicky, and Mama are at the barbeque, Mama takes a drink of her juice or whatever it is. But when you see her put the drink back down on the table it is at the same level as it was, when she picked it up.
Corrected entry: When Bobby is studying for his exam, his mom finds out he is playing football and going to school. She says he will fail the exam but Bobby never told her about the exam.
Corrected entry: During the Bourbon Bowl, "Meaney" carries the ball on offense but he is wearing 72. It is illegal for 50-79 to touch the ball on offense. Those numbers are reserved for lineman only.
Corrected entry: The kid who plays the water boy in flashbacks changes. In the flashback to when he was a kid getting ready to hit the player with the spoon, it is a long brown haired kid with bushy eyebrows. But when he has the flashback about girls and how momma thinks they are the devil, it is a shorter haired kid with larger eyes. They seem to be about the same age.
