"Leave It to Beaver" TV-Series 1957-1963

family sit-com with:

Barbara Billingsley (June Cleaver)
Hugh Beaumont (Ward Cleaver)
and, of course, the eponymous:
Jerry Mathers (Theodore 'Beaver' Cleaver)
usually notable for "the filthiest line in a sit-com":

Barbara Billingsley was asked about June Cleaver's remark,

"Ward, don't you think you were a little hard on the Beaver last night?"

The TV mom replied, "I don't remember saying it, but I must have, I''ve seen it on t-shirts."
