This week, we tackle not one but two episodes the zaniest of zany comedies Three's Company and try to decide once and for all: Roper or Furley. In "Ground Rules," Jack, Janet, and Chrissy try to establish some rules for alone or alone-with-someone time in the apartment, and Jack has a man-to-man discussion with Mr. Roper about "building shelves." In "Double Trouble," Jack has to convince Furley that he has a macho twin brother named Austin. Wait till Furley tries to throw a party...for both of them!
