To be truthful here, I’ve never seen an episode of “Head of the Class”. It premiered in 1986 and by then (at the age of 25) I avoided watching sitcoms that featured a large cast consisting of kids. It wasn’t made for me, so I can’t say much about it. But I was a big fan of “W.K.R.P. in Cincinnati” and “The Bob Newhart Show” and “Mary Hartman, Mary Hartman” (where he appeared as Doctor Williams for over a dozen episodes).

And yes, I realize that he joined the cast of “One Day At a Time” in it’s last season, but I’d stopped watching it by then.
