Automatically, all things Batman are cool. I don’t care if it is the Bat Dance (either by Adam West or the song by Prince), it is cool. So the Bat-Dana is cool, just 'cause.
The Bat-Dana is similar to a bandanna but cooler because it has Batman on it and a really funny name--and by funny I mean they pulled off a pretty good made-up word (and I know made-up words). So, this just leaves one thing: why don’t you have the Bat-Dana yet?
