I was trying to think of a sitcom past or present that featured a dad who was single (divorced, widowed whatever) and had no help. We have had shows like Alice and One Day At A Time that featured a single woman raising a child or kids on her own with no help, but I can’t think of a father doing this.
The Great Gildersleave, The Courtship of Eddie’s Father, Diff’rent Strokes, Family Affair and Bachelor Father all had housekeepers or “manservents” to help them.
My Three Sons had a grandfather, then an uncle help. My Two Dads needed not one but TWO fathers to raise that little girl and of course Full House had not one, not two but THREE dads (effectively) to raise those kids.
The only sitcom I can think of that had a dad raising kids with no help was Hello Larry. Were there anyothers?
