1 mistake in The Visiting Aunts
Starring: Barbara Billingsley, Hugh Beaumont, Jerry Mathers, Tony Dow
Eddie Haskell: Look Sam, if you can make the other guy feel like a goon first, then you don't feel like so much of a goon.
Wally Cleaver: I don't get that.
Eddie Haskell: Of course you don't. That's because you never went to kindergarten with a home permanent.
Captain Jack - S1-E3
Trivia: The episode "Captain Jack" was the first time a toilet was shown on TV; the boys buy a baby alligator and Wally is shown putting it in the toilet tank. The network censors were so spooked by the thought of showing a toilet on television that they delayed the episode. And when the censors finally relented, the compromise allowed only the toilet tank to be shown, not the bowl.
