Besides holding a five-year grudge against a grinning teenage cashier at Subway who gave him an unasked-for senior discount, Sy has written for many TV shows including The Bob Newhart Show, Taxi, MASH, Rhoda, Maude, The Wonder Years, Sister/Sister, Northern Exposure, Sanford, Gimme a Break, and Frasier. Several of his plays have been produced and he also writes a syndicated newspaper column. When not writing Sy enjoys hiking and taking naps (the hiking part is a lie).
