In the fourth season of Mad About You, Paul (Paul Reiser) and Jamie (Helen Hunt) Buchman deal with issues that could potentially break up their marriage. As they start planning a family, they are faced with infertility. When both decide to shake up their careers, one of them loses their job. And then there is the possibility of infidelity, when both Jamie and Paul are tempted outside of marriage. In a testament to the writers' sharp scripts and adroit acting by the leads, Mad About You manages to find humor during some bleak scenarios.
