From Scrubs Season 1 Episode 9 "My Day Off"
DR. KELSO (to Dr. Cox, who isn't wearing a lab coat): Dr. Cox, did you get my memo reminding all senior staff that lab coats must be worn at all times?
DR. COX: You know I did get it there, Bob, and at first I just threw it away. But then I decided that wasn't a grand enough gesture. So I made a replica of you out of straw and then I put my lab coat on it with your memo in the pocket and then I invited all the kids in the neighborhood to come over and light it on fire and whack it with sticks.
