I'm not even kidding... we actually just finished a full-on musical episode of Batman: Brave and the Bold. And if you can make it to the San Diego Comic-Con Friday morning at 10, you can watch it for free! I know it's hard to believe, but look at this (or this or this).
If you can't make it to San Diego, I think they'll air it in the fall, so please be patient. I'd love to post a teaser of some sort, but I don't think I'm allowed to, so here's something entirely different.
