YMMV / Barney Miller S 4 E 15

• Aluminum Christmas Trees: It might seem bizarre to a 21st-century viewer, but in The '70s there was much debate over whether marital rape was a thing. 47 states, including New York, actually had the Marital Rape License written into law. The highly publicized Oregon v. Rideout case, in which John Rideout was acquitted of raping his wife Greta, happened in 1978, less than a year after this episode aired.
• Unintentional Period Piece: The shockingly casual attitude towards marital rape, and indeed the idea that marital rape wasn't even illegal, is very, very 1970s.
• Values Dissonance: All the men in the squad room simply take it for granted that a man is entitled to rape his wife. The only half-nod towards sanity comes when Barney suggests that Mr. Lindsay should try to set a romantic mood.
