During rehearsals for this episode unbeknownst to the actresses, several members of the prop department had photos taken of themselves in exaggerated erotic nude or semi-nude poses and compiled them into the prop calendar "The Men of Blanche's Boudoir." The director had it filmed, and when the Girls saw the calendar for the first time on set They promptly fell into hysterical laughter. Afterwards each woman received her own copy of the calendar, signed by the prop department. McClanahan's copy was auctioned after her death, selling for over $4000.
Near the end of the episode, when the girls are in a diner, the exterior shot before the beginning of the scene is of "The Roadside Diner" (its real name) which is (as of 8/2012), and has been in business for decades. It's in Wall Township, New Jersey, a few miles outside of Farmingdale, NJ, just west of the Collingwood Circle. It's been the location for scenes in several movies over the years.
The only time in the past 200 years that snow was seen in Miami was 1977
