Gov. Chris Christie brought some of his sharp wit - and a suit pocketful of cream-filled doughnuts - with him on the “Late Show with David Letterman,” Monday evening, sitting down with his “favorite” late-night talk show host who’s frequently joked about the governor’s weight.

“If the joke is funny, I laugh, even if it’s about me,” said Christie, who told Letterman he found about 40 percent of the jokes funny.

Despite the girth, Christie assured Letterman he’s in good health, describing both his blood sugar and cholesterol levels as “normal.”

“I’m the healthiest fat guy you’ve ever seen in your life,” Christie quipped, to which Letterman responded, “That’s your campaign poster right there.”

At one time, Letterman told Christie he thought he’d be re-elected as governor this year, to which Christie jokingly asked if that was an endorsement. Near the end, Letterman said “I love you being governor of New Jersey.”  

Christie mentioned his favorite jokes Letterman has made about him, one focusing on his 50^th birthday (“He blew out the candles on his cake…and he wished for another cake”) and on Super Bowl snacks ($1 billion will be spent on potato chips this Sunday…and that’s just at Gov. Chris Christie’s house).

About midway through the interview, it took a more serious turn, when the two talked about post-Superstorm Sandy rebuilding efforts.

“It’s still awful,” Christie said about the aftermath, despite much of the debris having been removed.

The governor then elaborated, saying there were some 42,000 families who’re still homeless, staying in temporary apartments, hotels, or with family and friends. He said there are still some 80,000 businesses that have yet to reopen.

He said he’s hopeful now that the Senate passed, and President Obama signed, the $50 billion-plus Sandy relief package, much of which will come to New Jersey within a few weeks, many residents can rebuild and businesses can start to reopen. He hopes to have grant programs set up to accomplish those goals.

Christie also talked briefly about his emotional reaction about House Speaker John Boehner’s decision to postpone the Sandy relief bill vote, following the fiscal cliff resolution. Christie said he was bothered that his phone calls were not being returned.

“I started getting more and more pissed off,” he said, a remark that was received with laughter from the studio audience. “Just, you know, answer the phone.”

He added that in speaking with Boehner, he was “less gentle privately than I was publicly.”

About the possibility of running for president in 2016, Christie said, “I got to win in 2013…That’s my goal.”

“I’m nowhere near making that decision,” he said, adding that much can change in the next few years. “We’ll see what happens in the future.”
