Character mistake: In the scene at Roger Podacter's condo building, you hear the reporter mention that he allegedly leaped to his death from his own 20th story balcony. As the camera pans down, you can see the flashlights and people up on his balcony doing the investigation. This is the 2nd from the top floor. If you count the floors as the camera moves down, there are more than 20 floors to this building. The number is actually closer to 30. Even though it is difficult to get an exact count of the floors, it is still possible to tell with 100% certainty that his unit was on a floor higher than 20.
Character mistake: Ace claims the stone he found is triangular cut Orange Amber from a 1984 AFC Championship Ring. The stones in the actual 1984 AFC Championship Ring were not triangular cut Amber, they were round cut Diamonds.
Chosen answer: That scene was cut originally by the director Tom Shadyack because the scene did not support the story and thought it slowed the film down. (And the scene was cut from the US version as well.) It was added back later in TV versions of the film. Fan enjoyed the scene so much they asked it be put back in the film version. I know the DVD has it because I own it. It's hilarious!
