If Odysseus is enjoying himself, I can't really blame him. He was dragged off to a war he didn't want to go to, spent ten years trying to get home after ten years of a stupid siege, and he comes home to find this bunch of idlers, layabouts and scroungers have taken his home over---I'd be just as pissed off as he is.
But then, I always thought that Mr. Toad and his friends were more merciful to the Wild Wooders who'd taken over Toad Hall than I would have been.
