If you don't know the answer to this, then it might be time to catch up on some basic human knowledge.
What has a head and a tail but no body?
Most living things have a head, and plenty of them have a tail. It's pretty unusual, though, for something to have a head and no body. Plus, this thing (whatever it is) also has a tail.

If there are 12 fish and half of them drown, how many are left?
This might seem like a basic subtraction problem. After all, as long as you remember elementary school math, you should know what half of 12 is. Before you charge ahead, however, read the question one more time. If there are 12 fish, and half of them drown, how many are left? Oops. The answer to this one should be as easy as pie and certainly easier than fishing. Anyone with common sense should be able to get this question right.

If you put a coin in an empty bottle and then insert a cork into the neck, how could you remove the coin without taking out the cork or breaking the bottle?
You might have needed to read that question twice, and that's okay. You have a bottle. You have a coin inside the bottle. The bottle is sealed with a cork. How do you get that coin out, if you can't remove the cork? This isn't a seventh grade science experiment, and once you realize the answer, you'll groan. Read it again and then guess. If you put a coin in an empty bottle and then insert a cork into the neck, how could you remove the coin without taking out the cork or breaking the bottle?
What star is closest to Earth?
