What has a neck but no head, shoulders but no arms, and a body but no legs?

A bottle.

Did You Know?

This riddle works because bottles have parts named after human anatomy — a "neck" (the narrow top), "shoulders" (where it widens), and a "body" (the main container)! The oldest known glass bottles date back to 1500 BCE in ancient Mesopotamia. Modern bottles can take up to 1 million years to decompose in landfills, which is why recycling them is so important.
