Twenty Good Years is a short-lived American sitcom created by Michael J. Leeson and Marsh McCall, and starring John Lithgow and Jeffrey Tambor as mismatched friends—impulsive surgeon John Mason and widower judge Jeffrey Pyne—who decide to live life to the fullest after realizing they only have 'twenty good years' left. Thirteen episodes were produced, with an NBC premiere of October 11, 2006; however, due to low ratings, it was canceled after only four episodes and replaced by a block of specials. The unaired episodes have never been released, and only the pilot can be found online.
