Continuity mistake: When Will Stockdale is at the Purple Grotto, at one point the cup full of liquor is at different levels.
Factual error: The sergeant in the opening credits is not Air Force as the badge is reversed. Air Force are point down and army is point up.
Factual error: While a car radio is playing, the announcer identifies the station as WQUID. United States radio stations are identified by three letters or four letters, never five.
