Party on Wayne...

Schwing!

I think a little red rope licorice dispenser might help some of the folks understand.

BTW. Why is vader calling batman by his real name and batman calls vader by his alter ego, although batmans real name is NOT known while vaders real name IS known?! i'm thinking too much about it...

Then again, I don't think Batman is aware that Darth is not his real name and Vader has obviously jedi mindtricked Bruce into revealing his identity. Also, yes.
