Why do I laugh at the dying owl?

Why did I laugh when the owl died? Can anyone explain to me why I find it hysterical when Mr. Owl, from The Owl who Marries a Goose, sinks to his watery doom? I have a theory, but it's probably wrong:
He's an owl. He's not a goose. He physically cannot swim. But I found his love for Mrs. Goose to be beautiful and compelling. The reason that I think I find it funny is because Mrs. Goose lets him die! Her husband risks everything for her, and she realizes that he's gone too far, and she makes him decide for himself whether he wants to die with her or whether he will stay on land where he belongs. The problem is, why is this funny? Surely she loves him, right? Or at least she used to, because she married him by choice. So what changed, or did anything change? Does she no longer love him? Is she sick of him? It doesn't seem like he did anything wrong. Perhaps if this film was in my language, I would not feel conflicted right now. I feel that this film is a very cultural film and because I am not an eskimo, I do not try to understand it from their point of view, but I would love to have a native Eskimo explain it to me from their point of view.
