Joker makes a reference to the 1995 film Apollo 13 when he says, "Houston, we have a problem." ?
really I think he was sane enough to know the real event's of Apollo 13, and smart enough as well, but was way to crazy at the time the movie Apollo 13 came out to see it at the Gotham Cineplex Chasemarc (talk) 18:15, April 7, 2013 (UTC)
