The first of two subsequent season 3 "clip shows" which are primarily old clips from previous episodes. In television this tends to be a financially-driven decision so only a few minutes of new filming needs to be done. However, sometimes, clip shows are scheduled in order to work around actors' schedules.
Unbeknownst to the actresses, several members of the prop department took photos of themselves in exaggerated erotic nude or semi-nude poses and compiled them into the prop calendar "The Men of Blanche's Boudoir." Filming ground to a halt when the Girls saw the calendar for the first time on set and 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.
