According to Johnson:
"When I started racing, I didn't have much going for me, other than that I could say all the right things—almost to a fault. I can be freaking out inside, but then I open my mouth and I sound calm. I don't know where this device comes from. It helps me in racing because you never want to lose your cool. At the end of the day, and this is the truth, I'm still just a jackass from El Cajon."
