In an earlier episode June talks about the Rutherford party then in Wally Stays at Lumpy’s everyone is so surprised that Lumpy is having a party. June says it’s the first party he’s had since he started high school. I think the episode is Wally’s Chauffeur.

I remember June's comment about "the Rutherford party." It was just a few episodes ago.

Another inconsistency: in Nobody Loves Me, W&J are looking at an album (and June is telling Beaver not to breathe down her neck and Ward is scolding him about his dirty hands) and they are reminiscing about Wally and Eddie, at Wally's third birthday party. In a much earlier episode they established a later age/grade that Wally and Eddie met (need help on that one!)

Oh yeah! It was like the first or second grade, maybe third, one of those three I'm pretty sure!

Could it have been the episode New Neighbors when the Donaldsons moved in? As I recall June and Ward talk about how long Wally had known Eddie.
