When it’s raining, the cat is in the room or in the basement.

When the cat is in the room, the mouse is in the burrow and the cheese is in the fridge.

If the cheese is on the table and the cat is in the basement, then the mouse is in the room.

Now, it’s raining and the cheese is on the table.

Where are the cat and the mouse?

On an exam, a professor gave a female student a femur and asked:

— How many femurs do you have?

— Five!

— Wrong! You have only two femurs.

But the student was right. How is this possible?

5. Outsmart the ruler.

An autocratic ruler of an island didn’t want aliens to settle on the island. He wanted to seem like a fair monarch, so he made a law. According to the law, every person who wants to settle on the island has to make a statement on which their lives would depend.

3. According to the task, the cat can be in two places: either in the room or in the basement. But the cat can’t be in the room because the cheese is not in the fridge — it’s on the table. So the cat is in the basement. We know that the cheese is on the table and the cat is in the basement. This means that the mouse is in the room.

4. The student was pregnant. She meant her two femurs, the two femurs of her child, and the one that she was holding in her hand.
