Talk about being a "cool" parent. On this week's episode of Armchair Expert with Dax Shepard, the Scrubs actor spoke with Rob Loweabout his sobriety and the conversations they have with their children surrounding the use of drugs. "How old are your kids by the way, 'cause I'm wonder what you tell them about drugs? 'Cause I've been through it with my boys," the actor asked Dax Shepard. "I'm so glad you just said that because I was going to ask you the same thing," Shepard answered.
