THREE's COMPANY was never the same after The Ropers left. They had a better dynamic with the roomies...Mrs. Roper knowing the truth and no doubt suspecting all sorts of goings on while Stanley fell for the Jack is Gay bit. With Furley he was completly snowed by the ruse and just not a very bright character in general compared to the more realistic Mr. and Mrs. Roper. If this character had not been played by Don Knotts I can imagine him going the way of Lana. Norman Fell by the way was a very SMART man...he reluctantly agreed to the spin off but only after a clause that he and Audra could return after a year in case the spin off tanked like most spin offs do. Unfortunatly ABC waited an extra half season before canceling the Ropers denying them a chance to return and unfortunatly for fans of the first three seasons having them back as regulars...though that one guest appearance was a nice treat.
