To help Wally (Tony Dow) with his economics homework, Ward (Hugh Beaumont) offers to show the boys how to invest in the stock market. Wally and Beaver (Jerry Mathers) combine their savings -- 25 dollars apiece -- and are advised by Ward to place it in a safe stock. Unfortunately, they have invested their cash in a "sure thing" recommended by Eddie Haskell (Ken Osmond), and before long the stock has taken a disastrous downturn. Meanwhile, Ward stands benignly on the sidelines, almost as if he was armed with insider information! ~ Hal Erickson, Rovi
