I'm bp II, so I don't have too many crazy stories. I'll share what I do have, however.

During my first hypomanic episode, I thought that I was a genius who might discover time travel. So I learned basic Latin (in one month) so that I'd be able to communicate with the ancient Romans when I went to visit them. Quite ridiculous, right? But it got me to learn Latin (too bad I've forgotten most of it!).

I have many more ridiculous stories concerning depression...
