For all the female Batman fans (and I hope you are out there).  Actually, when you think about it, Batman could be considered the sexiest super hero of all time.  He's dark, mysterious, fit, doesn't talk much, and in his real life is a billionaire.  What a catch.

Of course, getting involved with Batman is a recipe for getting dropped into a vat of acid by the Joker.  Also, I've had women friends who have had to deal with psycho ex girlfriends of their current relationship.  Imagine the pain when your boyfriend's ex is Catwoman.  Something tells me it would be a little more crazy than getting a bunch of crazy texts.

If you are dating Batman (or some other guy with a psycho ex) I found some lame instructions on eHow.  Seems pretty rational to me.  I found a funny video about a psycho ex girlfriend.  Obviously staged, but still good.  

Of course, this shirt would also be appropriate for fans of Batgirl (why is it the old 70's TV shot Catwoman is so much hotter than like 90% of the women on screen today?).  I don't know how I feel about Batgirl.  On the one hand, she is pretty hot and Commissioner Gordon's daughter.  On the other hand, sometimes I feel like comics go through phases where they pander more or less to horny desperate teenage boys and end up leaving us with characters like Batgirl like discarded beer cans after a frat party.  

Of course, Batgirl developed into a really cool character on her own as Oracle.  Personally I don't think Batman needs a lot of help and should roll solo, but that's me.
