A little boy turned on and off the light and went to bed.

He was pondering on where the light has gone when he turned it off.

Next day he wrote a letter to the university.

A week later the university had answered his letter writing they have no clue where the light finaly has gone.

The boy was disappointed and went to the fridge for a cool root beer.

Wow, he sceamed loud, wow, here ist the light!

Since that time the boy told everybody about his discovery that the light after turning off finally ended up in the fridge...
