It’s never too late to learn how to swim, just ask this 7-foot-7 NBA big man.

Celtics center Tacko Fall took swimming lessons Wednesday alongside the children at the Charlestown Boys & Girls Club, according to Boston.com.

Fall, who towered over the youngsters, fully participated in the session, practicing introductory exercises like kicking and pushing off the wall. A round of “Marco Polo” capped the 30-minute lesson.

“I never learned how to swim, which is crazy because I lived right by the ocean back in Senegal,” Fall said. “I don’t want to say I was a homebody, but my mom wouldn’t let me go out a lot. I used to go to school and go back home, but I never really got to enjoy the beaches as much.”

Fall, who said he “can stand in most pools,” has previously had aquatic workouts, but this marked his first swimming lesson. He expressed an interest in returning to the club, so that he can continue his learning.

“I’m a natural,” he said, smiling. “I’m learning how to swim. This is it. I’m learning how to swim. Just give me a couple of days.”

Josh Kraft, CEO of the Boys & Girls Club of Boston, said Fall is teaching children the value of being willing to try something new.

“He’s showing these kids something real important,” Kraft said. “It’s never too late. It’s never embarrassing to try something you don’t know how to do.”

Fall, who turned heads during NBA Summer League in Las Vegas, will look to earn a spot on Boston’s roster when the Celtics tip off training camp next week.
