Hat tip to Pleasecopyme who found the class where Luke Sullivan teaches "simplicity" to the students at the Miami Ad school in Minneapolis, Minnesota. He opens with the bit of always using lions in all of your ads like he did when we interviewed him when he was in Denmark. But that's just to get under your skin, where he can teach you how to be good. The man was once a standup comedian, from that he learned that nervous is good.
If you can't catch Luke Sullivan live, I promise that his book Hey Whipple is just as funny. Read a bit from it under that link and you'll see.
