Tricky Questions

1.  A murderer is condemned to death. He has to choose between three rooms. The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven't eaten in 3 years. Which room is safest for him? 

2.  A woman shoots her husband. Then she holds him under water for over 5 minutes. Finally, she hangs him. But 5 minutes later they both go out and enjoy a wonderful dinner together. How can this be? 

3.  What is black when you buy it, red when you use it, and grey when you throw it away? 

4.  Can you name three consecutive days without using the words Wednesday, Friday, or Sunday? 

5.  This is an unusual paragraph. I'm curious as to just how quickly you can find out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it! But it is highly unusual, though. Study it and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out. Try to do so without any coaching!
