The Weymouth Educational Foundation is fielding teams for its 12th annual “Who Wants to Be A Know-It-All Quiz Night,” a fund-raiser for the Weymouth public schools. Players must be 21 or older and each team must have at least four and no more than eight members. The team entry fee is $250. Team costumes are optional, however, there will be a prize for the best one. Space is limited, and slots have sold out in the past, according to Helen Maloney, one of the organizers of the event. More information is available by calling her at 781-331-0048. The Quiz Night will be held April 5 at 7 p.m. at the Weymouth Elks.
