Sam walked for thirty minutes in the pouring rain without getting a single hair on his head wet. He didn't have a hat or an umbrella and his coat had no hood. How did he do that?

Why this works

This riddle plays with our expectations about hair and getting wet. It leads us to imagine scenarios involving rain protection, like hats or umbrellas, but the clever twist is that Sam is bald, meaning he has no hair to get wet in the first place! By revealing that he has no hair, the riddle surprises us with a simple yet effective explanation that turns our assumptions on their head.
