Mrs. Once-in-a-while - S6.E4

Mia and Frank have moved in with Mia's parents. They are trying to find ways to cultivate the joys of privacy anyway. Casper's depression is now so severe that he has been hospitalized and Frank is in a dilemma, should he prioritize sex or his sick friend? Persistent attempts on the part of Frank and Mia to find "alone time" are wasted, and Frank admits that the father-in-law gets more sex than he does.
