When Stottlemeyer and Disher are talking in the garage, Disher's guitar strap has a wide shoulder pad over his shoulder when shot from the back, but when seen from the front, there is no pad, just a narrow strap.
$10 million in bearer bonds were stolen from the armored car. However, bearer bonds were discontinued in 1982 and it's highly unlikely that a bank would be transporting that much in value.
When the dentist tells Randy he has to extract the tooth, he administers an anesthetic right away. But this is not the way it's done. Before an appointment, a patient is given special directions, such as no eating or drinking for 6-12 hours before the extraction because, if a patient vomits while unconscious, the vomit can kill him if he aspirates it. There are a few more things that the dentist tells a patient to do to prepare for anesthesia, too. For general anesthesia, dentists do not use a face mask to administer gas because the sedative is administered intravenously. If nitrous oxide (laughing gas) is used, the gas won't actually sedate the patient. It will only make him feel sort of goofy, and relaxed, but he will be wide awake, especially when the mask is removed from time to time.
When Randy wakes up from the tooth extraction, he is able to speak normally, but he shouldn't. After a tooth extraction, gauze is placed in the empty spot where the tooth was and the patient needs to bite down on it to hold pressure for about an hour to prevent "dry socket" and to ensure that a clot forms over the exposed bone.
The dentist says they need to extract tooth number 3. That tooth is in the upper right but the dentist then looks at a tooth in the upper left.
