Cynthia Bush is the mother of Logan Bush from Bob's Burgers.
She is described as a 'hussy' by both Linda and Louise. She is stubborn to the point of getting into physical altercations, almost getting into them with the One Eyed Snakes and Linda. She is more wealthy than the Belchers, and has a snobbish attitude towards them and the restaurant. Despite this, she has an artsy side, as she and Tom named their son "Logan Berry Bush" (a decision she claimed they "didn't think [it] through"). She has some discipline issues with Logan, admonishing him for stealing Louise's bunny ears, and taking him a parenting seminar by Dakota Applebaum after calling her "the "b" word".
