“Leave It To Beaver! Starring...Barbara Billingsley, Tony Dow, Hugh Beumont and”...never mind.
Dirtiest line on network TV that made it past the censors:
“Ward, you were a little rough on the beaver last night”
I can envision a room of TV writers, betting the network would never allow that line to go on the air. The guy who wrote that line—and probably bet against his colleagues—probably picked up some nice pocket change that day.
