What has a face but never smiles?
Answer: A clock.
A clock has a face with numbers and hands, but it cannot smile. The riddle works because it uses the word “face” in two different ways. We usually think of a face as part of a person, but a clock also has a face where the numbers are displayed.
That simple double meaning is what makes the question feel tricky at first. Once you stop thinking only about people and consider everyday objects, the answer becomes clear.
Classic riddles like this are popular because the clue sounds almost impossible until one familiar object suddenly fits perfectly.
