Leave It To Beaver

Show generally

Continuity mistake: In season 1 (1957), Beaver is in grade 2 and Wally is 13 and in grade 8. Tony Dow was born in April 1945 and Jerry Mathers in June 1948. This means that Beaver/Jerry would have been 9 and Wally/Tony Dow 12, with a 3-year age gap. In the last (6th) season, Wally is a senior which indicates that he must have failed a grade. Meanwhile, Beaver is in 8th grade. Interestingly, the actors were also 3 years apart in age. At age 12 in 1957, Wally should have been in 6th/7th grade, which is more consistent with him being a senior in season 6.

Eddie Haskell: Not me! Your father doesn't like me.
Wally Cleaver: Why would you say that?
Eddie Haskell: On account of the way he looks at me when he opens the door. Sometimes I think he'd be happier to see Khrushchev standing there.
