Jimmy Kimmel knows that kids don’t always tell the truth. Because of that, he puts kids in a room, attaches them to a “lie detector” and asks questions to find out if they’re naughty or nice. It’s a great tool for Santa, but it’s a lot more fun for the rest of us. Kids will also say things that you may not expect, so Kimmel never knows what he’ll get when he starts asking questions. Check out the Jimmy Kimmel: Lie Detective Naughty or Nice spots for 2013:
