This episode makes me laugh at the near-riot in the restaurant, but it also frustrates me to no end. First, I had to agree with Ward - a cold Brussel sprout is as appealing as a soggy sponge (ugh). As the other reviewer mentioned, June's approach to the problem was terrible, and to me very out of character for her.
As a person who'd been a Julia Child fan from her early days on PBS - what might have worked was a better food presentation. If June had invited Beaver into the kitchen instead of making him sit alone at the dinning room table, cut a couple (as in 2) now-cold sprouts in half, melted a good amount of butter in a saucepan (no microwaves yet), and heated the halved sprouts in the melted butter, and to make them taste better, melted cheese over them (Velveeta would have been even better). Then they'd be hot, and taste like butter and cheese, not cold hard nasty round things that tasted like day old cabbage.
Not sure why the writers made June so sour (no pun intended) about the whole issue, though I can understand why she said he needs to eat what's good for him, but as in most things in life, there's usually a better way to resolve a problem without forcing a kid to do something - that never works and those are the things that stay in a kid's head - until they are spoken of at the therapist's office, years later...
