I wonder, if you did this with some smarter kos, would they be able to figure out how to get off?
In theory, yes-- if they're smart enough to realize they both need to jump at the same time. Seems more likely that one would try to escape without thinking about the consequences, or throw a tantrum, or do anything to overbalance, at least one of them is going in.
Darroth - There's something really funny to me about the whole Mister thing. Isn't there a whole category for anons using yukkuri catchphrases, too?
