Rob Reiner
"Butt Out" was written and directed by Trey Parker. Matt Stone said the episode was inspired by a desire to spoof both California's strict smoking bans and film director Rob Reiner; Stone said, "We try not to be, 'All right, here's the point we want to make.' But things like California's smoking ban and Rob Reiner animate both of us. When we did that Rob Reiner episode, to us it was just common sense. Rob Reiner was just a great target."
