Trading Places (1983)

Deliberate mistake: Eddie Murphy is giving his first party and tells everyone to leave. The valet holds all the coats in a perfect pile for the people to grab them as they leave. Although everyone rushes out of the party, it's very strange that the first person to leave takes the first coat, the second person the second coat and so on until the very last guest. No one stops to check if the coat they're taking is really theirs. (I guess it was shot this way to keep the good pace of the sequence). (00:43:55)
