Sneaking a peek at Beaver's report card, Eddie (Ken Osmond) prankishly changes the arithmetic grade from a D minus to a B plus. Fully aware that Beaver (Jerry Mathers) is hardly a Rhodes scholar when it comes to math, June (Barbara Billingsley) figures out that the grade has been altered. Beav, of course, insists that he hasn't tampered with his report card, thereby setting up the big situation of the evening; will truth prevail, or will our hero be clobbered for something that he didn't do? ~ Hal Erickson, Rovi
