David Jacob Conner, played by Michael Fishman, held the title of the family baby, until younger brother, Jerry, came along. Better known as DJ, he was the little brother we all loved to roll our eyes at and cock our heads at his eccentricities. His innocence played well in contrast to his strong-willed older sisters. Though he was as often referred to as "weird" by his sisters, DJ always knew how to make Dan and Roseanne smile as the family kiss-up.
Now a grown adult in the revival, DJ is a proud father of Mary, his daughter from his marriage to former classmate, Geena. Roseanne notably addressed DJ's childhood struggle to befriend Geena for being a person of color. He learned to accept and embrace his peer, whom he later wed.
