I wonder if it was the oversize, two-screen depiction of Anthony Weiner’s tweet that was the last straw. Or, if it was the “jokes” that bothered the GOP leadership gathered in New Orleans, exactly which joke it was that pushed the conference management to pull this ‘comedian’ off the stage:

A President Obama impersonator was pulled off the stage Saturday at the Republican Leadership Conference, after telling a string of racially themed jokes about the president.

The impersonator, Reggie Brown, took the stage at the annual presidential cattle call to the Bruce Springsteen song “Born in the USA” — an apparent allusion to the birther controversy. He proceeded to tell a series of off-color jokes poking fun at Obama’s biracial heritage and a gay member of Congress.

You know you’d like a sample of the “jokes”, so here they are:

• On Black History Month: “Michelle celebrates the full month. I celebrate half.”

• “My mother loved a black man,” but “she was not a Kardashian.”

• A picture was shown of Obama and the first lady when he took office. The impersonator then showed a picture of what the Obamas will look like when the president leaves office, and it was the characters of Fred Sanford and his sister-in-law, Ethel, from the show “Sanford and Son.”

Race wasn’t the only subject where the impersonator pushed the envelope.

• Of Tim Pawlenty’s decision not to criticize Mitt Romney at Monday’s debate: “[CNN’s] John King served him up a ball softer than Barney Frank’s backside.” (Frank is a gay member of Congress from Massachusetts.)

• Of Newt Gingrich’s approval ratings: Dropping “faster than Anthony Weiner’s pants in an AOL chat room.”

• There was also one moment where the original Weiner twitpic was shown on the large screens on either side of the impersonator, with no blurring.

Oh, and — ooops!

The jokes came after speakers including Mississippi Gov. Haley Barbour and Louisiana Gov. Bobby Jindal made pleas for Republicans to be civil in their criticism of Obama.
