Celebrity 'MAD' FADES OUT By People Staff Published on March 31, 1999 12:00 AM Share Tweet Pin Email Viewers will get a chance to say good-bye to Paul and Jamie Buchman on May 24 in a one-hour series finale of “Mad About You.” After seven years, the NBC comedy — which recently ranked a low 54th out of 128 shows — is filming the last chapter in the life of the Buchmans, played by Paul Reiser and Helen Hunt. Hunt has co-written and is directing the final show, NBC said Wednesday. She told “Access Hollywood” that Janeane Garofalo will guest-star — as the Buchmans’ daughter Mabel. (Mabel is two years old.) That’s all Hunt would say.
