If I think back to all of it, this show started it all. For some viewers who have not watched it, and best remember Bill Cosby from The Cosby Show. When ever this show will be shown in re-runs on T.V.Land. Just might find this show very enjoyable. Bill Cosby and Robert Culp were perfectly cast has Alexander Scott and Kelly Robinson two undercover agents going on dangerous missions and enjoying sight seeing. This show in many ways tried not to be to serious or to silly. It is a great blend of action and humor.
