A hard hat is the primary means by which all humans cover their heads. They are either considered highly fashionable, or else required to be worn by international law. Humans not only wear hardhats in typical situations such as oil rigs or ruby crystal mines, but also during a variety of other endeavors such as:
- Robbing a bank
- Driving a tractor trailer
- Reading meters at a hydroelectric plant
- Designing doomsday weapons
- Going to a museum.
