This is a riddle I remember coming up with a very long time ago. See if you can solve it. I don't know if anyone else had actually shown this to the internet, so I suppose I really am the creator.
One man inside a room, four sides made of concrete, the ceiling and the floor as well. There's a table and a mirror in there. No door or windows. How does the man get out?
There was a house with four walls, each wall pointed south. There was a window on each wall, and a bear walked past one window. What color was the bear?
