Beaver has to go to the dentist, so June picks him up in the middle of the day. It so happens report cards are being handed out, so Gilbert brings Beaver's by the Cleaver house. Eddie and Lumpy are waiting for Wally, who's upstairs--and take the report card from Gilbert.

Eddie proceeds to alter Beaver's math D- to B+, figuring Beaver would get blamed for changing it, and get in trouble. He was right. But Eddie didn't figure on Wally putting two and two together.

So Eddie phones Ward and apologizes.

Was this the worst thing Eddie ever did? What might change in the modern world?

Its one of the worst. He should have come clean sooner. It was kind of a crappy prank, but then again I got handcuffed for one of my pranks so...

I think that Ward was incredibly (not to mention, inexplicably) magnanimous when he told Eddie that if he pulled one more similar stunt, then that would be it for Wally’s friendship with Eddie after having caused SO much strife within the Cleaver family.

After this nasty prank, I think that Eddie would have been about as “welcome” at the Cleaver home as Martin Bormann or Osama bin Laden would have been.

And, I don’t think that anything would change (for the better) today in 2026.
