Pet Rock

A pet rock is a pretend pet that is simply a rock that people act like is a real pet. It was popular in the 1970s and was created as a joke by a man named Gary Dahl. He put the rock in a box with funny instructions about how to care for it (like you would care for a real pet) and people thought it was funny and started buying them.

Now, people still like to have pet rocks as a joke or just as a fun thing to have. It's important to remember that a pet rock isn't really alive and can't interact with you like a real pet can. It's just a pretend thing that you can have fun with.
