The Ricardos Visit Cuba - S6-E9
Trivia: In Uncle Alberto's favorite cigar store, there is a Puerto Rico poster on the wall. Since the episode aired in 1957, it was a bit of foreshadowing promoting the migration of Cubans to Puerto Rico ahead of Fidel Castro's revolution in 1959. (00:17:11)
Ricky Has Labor Pains - S2-E19
Trivia: After Lucy's baby shower, one of the gifts she received is a baby doll in a box lying on the couch, that Ricky picks up and smiles at. The actor has a reason to smile, as this doll is the "I Love Lucy Baby" doll which came in a box that had a small drawer with accessories, and was sold in stores. (00:09:30)
Answer: According to Snopes.com, there is no definitive answer, but the mid-1960s is the most verifiable date with "The Munsters" being cited as the first, although others claim "The Brady Bunch" showed the first couple seen in a double bed. An early TV show from the late 1940s titled, "Mary Kay and Johnny" is also thought to have shown the married couple's bedroom as having a double bed, although probably not with them in it. However, this was when TV was aired live, and there are no surviving episodes, only anecdotal accounts.

Something that is funny is that in the movie "A Christmas Story," they show the parents having two twin beds in their bedroom. In a real situation, they should have shown them having a double bed. Lucy and Ricky had twin beds pushed together in an early episode, which would have been pushing television boundaries in that time.
