Jane Wyatt and Robert Young — Jim and Margaret Anderson on the hugely popular family sitcom Father Knows Best-– appear to be riding a bike. Or maybe it’s just a handlebar and basket. Anyway, they seem happy — and that’s all that matters. Father Knows Best, which segued from radio to television in 1954, first aired on CBS, then moved over to NBC from 1956 to ’58, and finally back on CBS for its final seasons, in 1959 and ’60.
