Tonight, Warner Bros. TV held their Night of DC Entertainment special event in Hall H at Comic-Con, where everything was going smoothly until an unexpected visitor showed up. Yes, The Joker decided to crash the Gotham panel. And he managed to whip up a bit of chaos and confusion that certainly made the night memorable.

Earlier in the week, Gotham star Cameron Monaghan surprised everyone when he posted an Instagram photo of his slow transformation into The Joker. This was followed by leaked set photos of the actor in a straight jacket. Maybe attempting to one up Suicide Squad star Jared Leto and his method means of becoming the Joker, Cameron Monaghan surprised everyone when he suddenly popped out of nowhere inside of Hall H to steal the mic away from a fan during the Q&A portion of the Gotham Season 2 panel. He pointed to Ben McKenzie on stage and screamed, "This is for Detective Gordon. Would you say you have a high pain threshold?"

The actor was then tackled by security guards and dragged out of the auditorium. Ben McKenzie responded by screaming back at the villain that he would be stopped. It isn't known if the security guard portion of the stunt was staged or not, and at this time, there are only photos, as no video was allowed inside the panel. We've collected a couple of the photos, along with a video that shows all of the Gotham cast on a bus heading to the event.
