Vanity Fair magazine (April 27) introduced a barrel of jokes about political figures Cecily Strong delivered at Best White House Correspondents’ Dinner held on April 25th in Washington under the headline, “Cecily Strong’s best White House Correspondents’ Dinner jokes.” The following is one of them:
“Mr. President, thank you for taking time off of Jimmy Fallon’s show to be here,” Strong said. One joke that had Obama slapping the table in laughter: “Your hair is so white now, it can talk back to police.”
I know asking the meaning of a joke is boorish, but I don’t understand why you can talk back to police when your hair is white.
Is it because a senior person (whose hair is white) is regarded as sensible or authoritative, or politically incorrectly, white hair makes black look white? If it's the latter, why did Mr. Obama tapped the table in laughter to such a risque joke? I’m 82 years old, but I’m not sure whether my gray hair works in arguing with police. What does the above line mean?
