Do you remember Robin's costume from the 1997 movie Batman & Robin (yeah, the one with the armoured nipples)? What happened to it? No it's not destroyed. The original owner of the outfit, Chris O'Donnell still has it at home, keeping it out of harm's way.
He revealed this and talked a bit about it last night as a guest on Conan O'Brien's show.
