Jerry Brown Challenges Chris Christie To Three-Mile Race (VIDEO)

New Jersey Governor Chris Christie had choice words for California Governor Jerry Brown at the Republican National Convention last week, telling the crowd that "California made a bad choice by going with an old retread."

But at a United Food and Commercial Workers Local 770 meeting on Friday, Brown had a few words of his own.

"There's nothing wrong with being a little retread. Not as much hair, I've slowed down a little bit," said Brown. "But I have to tell you, I ran three miles in 29 minutes two nights ago. And I hereby challenge Governor 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."

The crowd exploded with laughter and applause.

At the RNC, Christie also criticized Brown's age, saying that when Brown challenged Jimmy Carter for the presidential primary, Christie was only 14.

"I may know a hell of lot more than you," Brown said about Christie at the meeting. "Because when you were 14, I was passing the Farm Labor Bill. I was passing worker protections in California."

All in all, Brown took the criticism in stride.

"It's the first time I'd ever been attacked at a Convention," said Brown. "So I feel that I've finally come into my own."
