Riddle: What has 3 feet but cannot walk?
Answer: Yardstick

Need a hint?

It’s used to measure things, and it’s exactly as long as a yard.

Answer and explanation (spoiler!)

The answer is a yardstick.

A yardstick is a measuring stick one yard long, and one yard equals 3 feet. So it “has” 3 feet, but it can’t walk anywhere.

The riddle uses the two meanings of “feet”: the ones you stand on, and the unit for measuring length.
