How do you get out of a room with four walls no windows no doors and all that you have with you is a 2 by 4 wooden board and a mirror?
== == Ram a hole in the wall with your 2x4 board, crawl out,
then hang the mirror over the hole. OR Look at yourself in
the mirror, break the board in half because 2 halfs make a whole
and crawl through the hole (simple math!). OR You look in the
mirror to see what he saw, you take the saw and cut the board in
half, then put the two halves together because two halves make a
"hole" then you crawl through the hole.
