The first 'dating' episode in a long while. Mary has a serious romance with Joe (Ted Bessell) who likes public displays of affection but has never told Mary "I love you", which bothers her.
The romance also kind of bothers Lou, Murray and Ted. These are the funniest scenes of the episode.
I don't generally like 'dating' episodes and I found Ted Bessell annoying and unappealing here. But overall this is a pretty funny and well-done episode. There's a twist at the end - unexpected but not entirely unbelievable.
Beth Howland who was previously Mary's prickly friend turned love rival Linda Foster in episode 'Have I Found a Guy for You' has a walk-on playing quite a similar role.
David Groh and Valerie Harper from 'Rhoda' make a cameo appearance.
The tag suggests make-up sex will follow. But didn't Joe just usher Joan out of his apartment? Maybe that's why Mary likes him so much.
