Corrected entry: When Ward is reading the article in the paper about Beaver saving a girl from drowning ("Local Boy in Lake Rescue"), the headline spells his name "Theodour." The misspelled headline is shown twice. (00:11:25 - 00:13:10)
Leave It To Beaver (1957)
1 corrected entry in season 4
Starring: Barbara Billingsley, Hugh Beaumont, Jerry Mathers, Tony Dow
Wally's Practical Joke - S6-E35
Visible crew/equipment: When Eddie Haskell comes over to scheme getting back at Lumpy, just as Eddie, Wally and Beaver are heading up the stairs, a mike boom is visible in the upper left corner.
June Cleaver: Dear, do you think all parents have this much trouble?
Ward Cleaver: No, just parents with children.
Trivia: Phyllis Coates, who plays the new neighbor Mrs. Donaldson, played Lois Lane in the first season of the Superman TV series in the 1950s.
Correction: I believe the misspelling of Theodore was intentional since later when Beaver read it he tells Wally "They misspelled my name."
