Once again, Lucy (Lucille Ball) decides to play matchmaker. This time her victims are middle-aged bachelor and bachelorette Sam Carter (Milton Frome) and Dorothy Cooke (Sarah Selby). Determined to demonstrate the joys of married life, Lucy uses her own "blissful" relationship with Ricky (Desi Arnaz) and Little Ricky as an example. Unfortunately, things go terribly awry as Lucy tries to entertain Sam and Dorothy in her home, with neither her husband nor her son in any mood to cooperate. The evening turns into an unmitigated disaster -- to which Sam and Dorothy react in an entirely unanticipated fashion.
