Whit Sunday, the seventh Sunday after Easter, is the day for a strange food-throwing custom at St Braivels, Gloucestershire. After the evening service at the church, people gather near a wall by the castle, and bread and cheese are hurled into the crowd. Everyone scrambles to grab as many pieces of food as they can. The locals of St Braivels have been hurling bread and cheese since the 13th century, when the custom began probably as a payment for the villagers' right to cut timber from a nearby wood.
