Heh. I love this kind of story, but the only other one I can remember off the top of my head is the Star Trek DS9 episode which built upon the Trouble With Tribbles episode from the original series.

*snicker* Very amusing. You have some terrific characterizations here, and I can really picture Happosai trying something like that. The deranged logic was also entertaining. Great job all around. Thank you for writing and posting this story on the internet. I had a great time reading it.
