Sir John Falstaff, in Windsor and short of money, decides to woo Mistress Ford and Mistress Page, prosperous citizens’ wives, and sends identical letters to them. This leads to a side-splitting evening filled with mischief, schemes, a buck basket, a wood full of fairies and one pair of horns in “The Merry Wives of Windsor.” Evening performances will be at 7:30 p.m. Thursdays, Fridays and Saturdays and 6:30 p.m. Sundays.
