Now that we've got a black President and first lady, he's just reversing it in a mildly amusing way. It would have been funnier if he'd said something like, "A white President? That's absurd." But whatever, it was a joke.
It would be like saying, " I don't think America is ready for a white Heavyweight boxing champion." (because they're all black, get it? Rim shot)
It's not the funniest joke ever told, but I don't think Mr. Moon President should have made a big deal out of it. People shouldn't take themselves so seriously.
Still don’t think it’s “funny”. We’ve already had “white” first ladies. Someone might need to clue crazy Bobby in on that. Not funny. He should have said something like, “I don’t think America is ready for an illegal alien first lady with a stolen I.D.”. Now that’s funny.
