Dax: I've had plenty of crappy jobs, but the only job I've ever really dedicated myself to has been acting. It's my life.
Dax Shepard: I do attribute my success to Punk'd. The opportunity to improv helped a lot to showcase my exact sense of humor. It usually takes other comedic actors a long time to show what they can do because they have to work with other people's scripts. But on Punk'd my options were wide open and I was free to do my own thing.
