In 1989's 'Batman,' Jack Nicholson (as the Joker) famously wondered out loud, "Where does he get those wonderful toys?"

Fast forward to 2012, and fans of the latest Batman franchise are wondering the same thing. And while we may not know exactly where the caped crusader sourced all that cool stuff, we now have a pretty good idea of how much it would cost.

In anticipation of this weekend's release of 'The Dark Knight Rises,' the blog Centives, which is run by Lehigh University economics students, analyzed 'Batman Begins' and 'The Dark Knight' to calculate what it would take to actually become Batman, taking into account a point by point list of items (with some substitutions to account for things like "memory cloth" that don't yet exist).

And after tallying up everything from Alfred's salary to martial arts lessons to private jets, not to mention all that equipment recommended by Lucius Fox, the students estimated the cost of being Batman could run you as much as $2.8 million.

But while that may be well out of your reach, the bloggers estimate Bruce Wayne's net worth to be almost $12 billion -- so he might consider that pocket change.
