Tlachtli (or ulama), the game the aztecs played, must be the most bizarre of all sports: it's played with a rubber ball that players must try to pass trough a vertical hoop (it was very small, and it was placed very high), using their elbows, hips and legs.

Sometimes losers were killed, sometimes their opponents had the right to undress them after scoring.
