Scott Baio after Happy Days concluded its run was lucky enough to grab this second series which gave him quite a few more years in front of the American television viewing public. Lucky because the whole cast revamped in the second season except for Baio and Willie Aames.
Charles In Charge's most current series that is like it is Jessie from the Disney Channel. He's a college student who pays his tuition as a live in Au Pere for a family with three kids. The first season the family was the Pembrokes, but for some reason the family never clicked with the public. So in the second season Baio comes back from summer vacation and finds a whole new family moved in with three kids, two girls and a boy of roughly the same ages and he has to make a case to be hired by the newly arrived Powell family. He does in that first episode and the run for seven years was assured.
The only other regular kept on was Aames who played Buddy Lembeck, Charles best friend who provided most of the comedy. In Eight Is Enough Aames was your all American kid, here he's your all American doofus. I mean who else orders patio furniture without a patio, that was the level of comedy Aames provided, but he was funny.
Like Jessie, Charles was always around with some good advice and ever ready to solve the problems of the Powell kids. Ellen Travolta was in several episodes toward the end and we learned she called him 'doodlebug' as pet name. That didn't help with discipline.
Charles In Charge was a clean wholesome show that had some good comedy and some sound advice for living as well.
