LISTEN: Caller Discusses His Grandmother's 100th Birthday With Mike Francesa

NEW YORK (WFAN) -- On Friday's show, Mike Francesa received a call from a listener who wanted the WFAN host to wish his grandmother, who was in the car with him, a 100th birthday.

Pat from Cedar Grove said his grandma, Fran La Sala, still works and drives to church.

"She's still witty. She's still smart," he said.

Francesa was impressed.

"Ask her what her secret is for her longevity," he said.

The answer: dark chocolate and coffee.
