1 trivia entry for season 2
Starring: Hal Linden, Max Gail, Ron Glass, Steve Landesberg
Uniform Day - S6-E17
Factual error: It is Uniform Day where they all have to wear their uniforms. The badges they all wear are those of patrolmen. The problem is that they are detectives and the NYPD has detective badges, which are distinctly different looking.
Dietrich: Was that Mrs. Miller?
Barney Miller: Yeah.
Dietrich: Past tense was unintentional.
