The teacher asks the class to one-by-one, come up to the front of the room and add to a drawing on the chalkboard. She knows Little Johnny isn't the best candidate to go first, so she asks Suzy to go up. She draws:

      /\
     /  \
    /    \
   /      \
  /        \

|            |
|            |
|            |

"This is our house where we all live," explains Suzy.
"Very good. Joey, come add to the picture." He draws:

      /\
     /  \
    /    \

"This is the door to our house."
"Very nice. Betty come on up." So she draws:

      /\
     /  \
    /    \
   /      \
  /\__/\__/\
 /          \
|            |

|     ___    |
|    |   |   |
|    |   |   |
|    |___|   |

"This is the roof of our house."
"That's good. Bobby, come and draw." So he draws:

     \ | /
     - O -
     / | \
      /\
     /  \
    /    \
   /      \
  /\__/\__/\
 /          \
|            |
|            |
|            |
|            |
|     ___    |
|    |   |   |
|    |   |   |
|    |___|   |

"This is the sun, to keep us warm."
"Good job!" By now, only Little Johnny has his hand raised, begging to draw. She can't think of any way that he could mess up the picture, so she lets him come up
And this is what he draws:

             ________  ________
            /        \/        \
           /                    \
          /         \ | /        |
         |          - O -        |
         |          / | \        |
         |           /\          |
         |          /  \         |
         |         /    \        |
         |        /      \       |
        /        /\__/\__/\       \
       |        /          \       |

         |     |            |    |
         |     |            |    |
