Hard hat

C'mon, Prime... everybody does it.

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 hard hats 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.
• Cleaning subway tunnels in New York
• Fixing a time-travelling crashed alien starship millions of years in the past from damage caused by bio-mechanical rhinoceros sneezes.
• Making evil morally ambiguous TransTech scientists suspicious.

The versatility of the hard hat in fact seems to be limitless.
