At a baby shower for Joyce's three nieces, Bob and Margaret freely admit that they aren't interested in having children, preferring instead to enjoy their life together and their careers. Their assertions are met with skepticism; the guests assume that they want to have a baby, but that they can't. Not surprisingly, Dr. Gilroy, the fertility specialist responsible for one of the niece's children, is revered as a god by all of those attending. When Gilroy arrives, he charismatically suggests that Bob become a sperm donor at his clinic. Bob likes the idea of propagating the Fish line and Margaret humors him until Guinevere latches on to the idea of having a baby -- and, unbeknownst to her, is in line for Bob's sperm.
