I’m the punchline of every bad intelligence test. I may not be bright, but I’m solid.

I have four arms but no hands, and I spend my life standing still while running in circles. I eat nothing but air, yet I crush grains into powder. Instead of pumping iron, I can pump water. I am often mistaken for a giant by those who tilt at me. What am I?

If you hunt you may find me. If you dig deep, you make me.

The day after tomorrow. First used in fifteen thirty five.

I have a head but no brain, a body but no blood. I get shorter the more I work, and my only job is to make your mistakes vanish into thin air. What am I?
