Carell was born at the Concord hospital, and his mum, Harriet Koch, worked there as a nurse for more than 30 years.
He and Emerson go “way, way, way back,” he said in the video posted on the hospital’s Twitter page Wednesday.
“I like to consider myself sort of an alumn[us] of Emerson Hospital because I was born there. I was voted Cutest Baby of 1962,” he added with a straight face.
Carell then paid tribute to the staff for their work during the coronavirus pandemic.
“Thank you, folks, for everything you’re doing. It’s greatly appreciated,” he said. “Keep up the good work.”
Though Carell was born in Concord, he grew up in nearby Acton. He still has a home in Marshfield, south of Boston, and summers there, according to the local Metro West Daily News. He also owns the Marshfield Hills General Store.
