Riddle: You are trapped in a room, with only a table and a mirror. No doors, no windows. The whole room is cement. The walls are miles long. The celing is miles high. You can't dig yourself out or bust through the walls or anything like that.
How do you get out?
(Hint: The way you escape is not actually possible, it is a cartoonish way you get out)
Answer: You look in the mirror and see what you 'saw'. Take the 'saw' and cut the table in half. Put the table to make a 'whole'. Go through the 'hole' to get out.
