You don't want to play elementary-style games with the Joker. No lava tag, no cops and robbers, no red light/ green light. That man takes things just a bit too literally! When the Joker says hot lava, it'll actually be hot lava! Cops and robbers will actually be cops and robbers! Red Light/ Green Light....well...let's just say you don't want to get caught by a red light. I think Jason Todd found out now that I think about it. Truth be told, the only person who knows what's going on inside the Joker's head is the Joker. Of course, you can attempt to channel the madness of the Clown Prince of Crime with this absolutely delightful 1.25 inch Joker Red Green Button.
