When Lucy's pregnancy cravings and preoccupation with a baby shower leave Ricky frustrated and overwhelmed, he begins to develop psychosomatic pregnancy symptoms of his own. A doctor advises Lucy and Ethel to give Ricky some special attention as a cure, so the women ask Fred to organize a men-only "daddy shower" for him. When Fred calls it a "stag party" in front of Lucy, curiosity gets the best of her and she must find a way to sneak into the event.

With the baby due at any moment, Ricky and the Mertzes carefully rehearse the trip to the hospital. But when the big moment actually comes, things do not go quite so smoothly. When they eventually get there, Lucy stays in labor for quite a while, so Ricky goes to do his new show at the club. He is in full tribal face makeup when the call comes from the hospital, and he rushes over still in costume.
