Ed's ex-wife, Liz was originally played by Janeane Garofalo in the original pilot that was turned down by CBS.
Stuckybowl (including the interior) was located in Northvale, New Jersey. (It used to be called Country Club Lanes and was closed down around 1997 before Ed moved in.) It has since been demolished to make way for adult condominiums.
Titled "Stuckeyville", the original CBS pilot was devoted to setting up the premise of the series. It featured Ed's string of misfortunes, his nostalgic return to Stuckeyville, and his fateful encounter with Carol. When the show finally reached the air on NBC, the entire CBS pilot had been edited down to a brief montage at the beginning of the NBC pilot.
