Cleaver?

And risk Wally getting so freaked out that he'd dump him as a friend?

To say nothing of risking Mrs. Cleaver summoning BOTH Ward and Mr. Haskell who'd likely have yanked Eddie by each. .. .ear and taken him to the nearest toolshed to have a long 'talk' with him about putting ALL thoughts of treating Mrs. Cleaver as anything besides a respectable married and . ..unobtainable MOTHER out of his head?!

Even Eddie wouldn't have been THAT brash or self-destructive!

Somehow I suspect June is an overly tall order for Eddie. But based upon his many compliments of her wardrobe, I do believe that a taboo or two might have crossed his mind every now and then.
