Birthday party. Pin the tail on the donkey. Except somebody's uncle has hung the donkey off the ceiling fan and it is spinning, and the tails are going up there one at a time whether you like it or not. Every tail sticks where it lands and rides the spin, shrinking the gaps for the next one. Thread the narrowing spaces, snipe the candies that sit right next to old tails, and hang on as the party gets faster, the fan goes wobbly, and everyone has had far too much cake.
