New Jersey Gov. Chris Christie said earlier this week that when California voters chose Jerry Brown as governor, they "made the bad choice by going with an old retread."
Brown responded while speaking to a local union group in Los Angeles. "There's nothing wrong with a little retread," he said. "I hereby challenge Gov. Christie to a three-mile race, a push-up contest and a chin-up contest. Whatever he wants to bet, I have no doubt of the outcome."
If you didn't know, Christie is overweight and Brown is 74 years old.
