Bank robbery is the criminal act of stealing from a bank, specifically while bank employees and customers are subjected to force, violence, or a threat of violence. This refers to robbery of a bank branch or teller, as opposed to other bank-owned property, such as a train, armored car, or (historically) stagecoach. It is a federal crime in the United States.

A scavenger hunt is a game in which the organizers prepare a list defining specific items that need to be found, which the participants seek to gather or complete all items on the list, usually without purchasing them. Usually participants work in small teams, although the rules may allow individuals to participate. The goal is to be the first to complete the list or to complete the most items on that list. In variations of the game, players take photographs of listed items or be challenged to complete the tasks on the list in the most creative manner. A treasure hunt is another name for the game, but it may involve following a series of clues to find objects or a single prize in a particular order.
