Additionally, the two have collaborated on Horizon: Fat vs Sugar, Horizon: Is Binge Drinking Really That Bad for You?, The Secret Life of Twins and Operation Ouch: Blow Your Mind. And in their younger and slightly fuller-haired days, Chris and Xand starred in a series called Medicine Men Go Wild, a show in which they did, in fact, go wild.
