"Pin the Tail on the Donkey" is a popular party game often played at children's birthday parties. In this game, a picture of a donkey is hung on a wall, and players take turns being blindfolded. They are then spun around a few times to disorient them before attempting to pin a paper tail onto the donkey's rear. The goal is to get the tail as close to the correct spot as possible while being unable to see. The player who pins the tail closest to the designated area wins the game. This activity encourages fun, laughter, and friendly competition among participants.
