Sometimes I get the joke, and other times, it flies right on by my head due to some factor I can't really explain that makes it unfunny. Humor is also a strange thing. I often wonder how it has come to exist, why humans possess it, and why certain people laugh at certain things. Just what IS it? What creates it? And why do I not share the same sense of humor as the majority of the internet? Hee. I think a lot.
I've never gotten superstitious about things like that. It doesn't feel satisfying enough that it'll do anything to increase the chance of capture. If the action was more satisfying, then maybe it would feel like something was going to happen. But I can understand that strange superstition from other peoples' points of view.
Oh, you looked up the story? But the whole magic of the thing is being surprised by how crazy it is when it starts off all normal. It's been spoiled now. I can only imagine how much less sense it must make as well to read about it rather than see it in action. But ah well. If you want to try it, you can, but there's no need to feel obligated about it. Different people have different reactions to all sorts of things, so it might not necessarily induce quite the reaction it did in me.
