Letter to Gorbachev was the sixth episode of Season 3 of The Golden Girls, also the 57th overall episode of the series.
When Rose learns that the young girls on her cadet troop are worried about nuclear war, she takes it upon herself to write to President Reagan and Premier Gorbachev expressing her concerns. Mikhail Gorbachev's U.S. representatives report that their leader was touched by Rose's letter pleading for nuclear disarmament and that he is eager to meet Rose — who, they all assume, must be a little girl, given her letter's naivete. As Blanche and Dorothy ponder how to break the news to Rose, Sophia tries to devise the perfect act for a talent show.

Dorothy: Hi, Ma.
Sophia: Give me your watch.
Dorothy: Sure. What do you want it for?
Sophia: I'm working on a magic act for the talent show at the center. [puts the watch in a bag] Abracadabra, one, two, three. [hits it with a hammer]
Sophia: Relax. Dorothy, was your card the ace of spades?
Dorothy: Ma, what the hell are you talking about?
Sophia: I think I got chapter seven and nine mixed up. This watch is broken.
Dorothy: Ma, Stan gave me that watch when we got married!
Sophia: Well, the marriage never worked, why should the watch?
