Joe Methany and the Evil Killer Clown

"I don't think anyone should ever be ashamed of intellectual curiosity about things no matter how bizarre or perverse they may seem," he says. "If you're not curious about something, how can you ever understand it? And if you don't understand it... I'm not saying that we're changing the world by being interested in true crime." A signed Joe Methany birthday card is now available for $140 on Etsy. The show airs Sundays and Mondays at 10 p.m. ET/PT on Investigation Discovery.
