The couple visited Philadelphia on Saturday and arrived Sunday in New York, where they toured the Harlem Children's Zone and then the Harvard Club, where Charles received an environmental award presented by former U.S. Vice President Al Gore, who won the honor last year.
At the children's facility, Charles took to the basketball court and made one poor shot before sinking a basket off the backboard, The New York Times reported.
Later, at the Harvard Medical School Center for Health and the Global Environment's award ceremony, actress Meryl Streep, who sits on the board, confessed in a speech she had been smitten by Charles for decades.
"When I was a little girl growing up in New Jersey, one of my goals was to marry the Prince of Wales," Streep said. "Now, as I look at you through my reading glasses, I have to appreciate you in other ways."
