BIDDEFORD, Maine (AP) — You may have heard through the grapevine that it’s Pi Day. That means a Maine teacher dubbed the “Pi Guy” is back at it.

Biddeford High School math teacher Jon Jacques always tries to make Pi Day fun through goofy antics, including musical parodies posted online. This year, he’s provided his take on Marvin Gaye’s “Heard It Through the Grapevine” featuring the Biddeford Singers, jazz band and Pi-inspired lyrics.
