Today, bobbing for apples is a popular party game. But it turns out, the quirky activity started as an 18th-century British courting ritual, according to the History Channel. In one set of rules, each apple was assigned to a potential suitor. The bobber would attempt to bite into the apple associated with her preferred beau. If she bit it on the first try, they would be destined for love. If it took her two tries, their love would sizzle and then fade. If it took her three, their relationship would be doomed.
