Robert Downey, Jr. became a bizarre zen master during an appearance on America's The Tonight Show Starring Jimmy Fallon on Wednesday (08Oct14) by dressing up in a traditional robe and donning a long wig to take part in an Intense Staredown comedy sketch. The actor sat silent opposite host Fallon on a fake mountain set and contorted his face in a series of hilarious expressions as a recorded voiceover shared his thoughts of wisdom about everything from world peace to stuffed-crust pepperoni pizza.
