Corrected entry: In the scene before the last play of the Burbon Bowl, Bobby Boucher is the victim of an unsportsmanlike conduct penalty and is injured, requiring medical attention. As a football rule, he would be required to sit out the next play, but he was in to throw the winning touchdown.
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.
Correction: The carbon/four bonds statement is wrong. CH5 is methanium. That's five hydrogen atoms bonded to one carbon.
This isn't quite accurate. In Methanium, 2 of the hydrogen molecules share 1 electron which means 2 hydrogens share 1 bond so that there's still just 4 bonds. Methanium is CH5+ or CH3 (H2) + not CH5. What is on the board doesn't indicate any shared electrons and couldn't exist. That being said, there could be a number of suggestion as to why this wouldn't be classified as a mistake, but this correction isn't one of them.
Correction: The sit out rule wasn't enacted in college football until around 2013. The Waterboy was released in 1998.
