Jack Donaghy is a cynical, slick, scrupulous network exec with an affinity for overtly backhanded compliments, which are usually directed towards Liz Lemon. Although his first priority is to run a successful business, Jack has struggled in that endeavor at times, and has often shown a human side that even he doesn't fully acknowledge is there.
