Does Anyone Know the name of this show? (PLEASE HELP!!)?

There was this show that I liked but I haven't seen this show in a while. I don't remember all the actors/actress in the show but I know Micheal J. Fox was in the show and he played Micheal Keaton. The family was the Keatons. I believe that they had 2 boys and 2 girl. The mom had blonde hair and the dad had grey hair. Does anyone know the name? It used to come on Nick At Nite but it took it off and they don't show it anymore. Some one please help me. My fiance' and my older sister have been fighting over the title of this show. My fiance keeps telling me this show isn't real and I know it is I was a fan of this show!
