Threes Company - Season 1

Jack moves in with Chrissy and Janet. On Jack’s move in day, Chrissy’s mother, who doesn’t know about him moving in, drops by unexpectedly for a visit. Karen (Mr. Roper’s niece) becomes bored while visiting, so Stanley sets her up with Jack figuring she’s “safe” from any fooling around with him. Jack misses Janet’s birthday for the date as well.
