January Jones loved the scene where Betty attacks one of the dining room chairs. The chair was made of balsa wood so it would break easily.
The subplot in this episode in which Heineken beer executives have a meeting with Sterling Cooper, and then Betty unknowingly buys Heineken for a dinner party (thereby proving Don's theory about Heineken's appeal to a certain class of housewives) was included because of a product-placement deal between "Mad Men"'s showrunners and Heineken. Many television critics commented on the irony of a show that has a pervasively jaundiced view of advertising nonetheless placing unironic advertising in their scripts.
The title of this episode has at least two meanings. It refers explicitly to the Catholic youth dance that Peggy helps publicize. It also refers to the 1955 Walter Lord book (and the movie that was made from it, A Night to Remember (1958)) about the sinking of the R.M.S. Titanic, an apt reference because what happens to Don and Betty in this episode spells the moment when their marriage starts "sinking" irrevocably. Walter Lord wrote "A Night to Remember" while he was working as a copy writer at a New York advertising agency.
With the scene set in Joan's apartment, this is the first time we've seen this character wearing pants.
