This final episode of Mad About You is set approximately 22 years in the future. Mabel Buchman (Janeane Garafolo), grown-up daughter of Paul and Jamie Buchman (Paul Reiser, Helen Hunt), follows in her dad's footsteps by producing a documentary film about her family. Several former series regulars and guest stars make cameo appearances as Mabel tries to trace the progress of her parents' marriage after a startling discovery made by Paul's sister Debbie (Robin Bartlett). Series star Helen Hunt directed this one-hour closer, which since its original network telecast has been divided into two half-hour episodes for syndication. ~ Rovi
