NEW YORK - New Jersey Gov. Chris Christie and David Letterman got a good laugh about the many fat jokes the comedian has made about the governor's ample girth.

Christie has termed his plumpness "fair game" for comedians. And during his first appearance on "Late Show with David Letterman" on Monday night, the outspoken Republican and potential 2016 presidential contender read two of Letterman's jokes that he said were "some of my personal favorites."

The governor also drew loud laughs when he pulled out a doughnut and started eating it while Letterman asked him if he was bothered by the digs that have been made about his weight. Christie said he wasn't, noting that he laughs at the jokes if he finds them funny.

Rosa Parks honored with a stamp

The U.S. Postal Service issued a Rosa Parks "forever" stamp on Monday, honoring the civil rights activist on what would have been her 100th birthday. The Postal Service unveiled the stamp during a National Day of Courage celebration at the Henry Ford Museum in Dearborn, Mich. Parks became a prominent figure in the civil rights movement when she refused to give up her seat to a white man on a bus in Montgomery, Ala., on Dec. 1, 1955.

Her defiance led to a boycott of the city's bus system and helped springboard the Rev. Martin Luther King Jr. into the national spotlight.

Deputy Postmaster General Ronald Stroman described Parks as "the epitome of courage." He served as a young lawyer on the staff of Rep. John Conyers, D-Mich., when Parks worked at Conyers' Detroit office.
