Ladder

Many people believe walking under a ladder propped up against a wall brings bad luck. This is because walking under a ladder is said to break the unity of the three member unit represented by a triangle (#22) either the family (two parents and a child) or the Holy Trinity (Father, Son, Holy Spirit). If you do walk under a ladder, fix your luck by crossing your fingers and spitting through its rungs three times. (Bonus fact! Ancient Egyptians included ladders in dead peoples tombs to help them reach heaven.)
