The 27-year-old NASCAR phenom swept last month's Charlotte races, the Winston and the Coca-Cola 600, and sits seventh in the Winston Cup points standings.
SI: Who's the one driver in NASCAR history you wish you could have raced against?
Johnson: Dale Earnhardt. If you wanted to race in Winston Cup, you wanted to race against the Man. When I daydreamed about winning my first race, it was with Earnhardt beating my bumper cover off as we came to the finish line.
SI: Fellow driver Jeff Gordon co-owns your team. Would you bump your boss to win a race?
Johnson: I'd bump him, but I wouldn't wreck him. We've had some pretty intense races for position, but we've done it without crossing any lines.
SI: Who would do better: You as the coach of the Dallas Cowboys or former Cowboys coach Jimmy Johnson taking a spin in your number 48 Chevy?
Johnson: Being that I don't know a damn thing about football, I'd have to say the other Jimmy Johnson.
SI: What's the craziest thing someone has asked you to autograph?
Johnson: Usually females are offering up body parts.
SI: Ever agree to sign one?
