The son of George (however, in Season 1, episode 20, Eddie gives his name as "Edward Clark Haskell, JR.") and Agnes, Eddie Haskell was the smart-mouthed best-friend of Wally Cleaver. The character, played in the original series by Ken Osmond, has become a cultural reference, recognized as an archetype for insincere sycophants. Ward Cleaver once remarked that "[Eddie] is so polite, it's almost un-American".
Eddie was known for his neat grooming—hiding his shallow and sneaky character. Typically, Eddie would greet his friends' parents with overdone good manners and often a compliment such as, "That's a lovely dress you're wearing, Mrs. Cleaver." However, when no parents were around, Eddie was always up to no good—either conniving with his friends or picking on Wally's younger brother, Beaver. Eddie's two-faced style was also typified by his efforts to curry favor by trying to talk to adults at the level he thought they would respect, such as referring to their children as Theodore (Beaver's much-disliked given name) and Wallace, even though the parents called them Beaver and Wally.
A weaselly wise guy, Eddie could be relied upon to connive and instigate schemes with his friends—schemes for which they would be in the position of blame, if (and usually when) caught. One of his most infamous pranks with the Cleaver boys involved fastening a chain around the rear axle of their friend Clarence "Lumpy" Rutherford's car, causing unplanned damage as the entire third member and wheels became detached when he tried to move the car. The prank has been repeated on police and gangster cars in scenes in the films American Graffiti (1973) and Gone in 60 Seconds (2000), respectively.
The New Leave It to Beaver
In the 1980s revival series, titled The New Leave It to Beaver, Eddie is now married to Gert, and they have two sons, Freddie and Edward Jr. (played by Osmond's real-life sons, Eric and Christian, respectively). Edward Jr. (nicknamed "Bomber") is enrolled at Vicksburg Military School, the result of Bomber having spilled grape juice on the Haskells' white carpeting. Both Freddie and Bomber have taken after their father.
