Been watching this on Antenna TV.

Three's a Crowd isn't exactly horrible but it's not even on the level of Three's Company's last couple of seasons. I think this show might've had a better shot at lasting at least a few seasons if there were at least occasional references to Three's Company along with guest spots by some of the characters. Supposedly both Joyce DeWitt and Priscilla Barnes were never offered the chance to appear on the show. But Don Knotts and Richard Kline were and turned it down. Although Richard Kline did make a guest appearance in one episode.
