DC All-Access has put together 20 Batman facts you probably didn't know. Not a bad list. some of them are pretty cool like the layout of Wayne Manor is the shape of a Bat, that no police official can turn on the Batsignal… it has to be done by a civilian or risk endorsing Batman's vigilante activities, that the first Batman villain team up was in 1944 with Joker and the Pengiun and the time you must set the clock to in Wayne Manor to open the passage way to the Batcave is 10:47, the time Bruce's parents were murdered.
