A man, who is sentenced to life imprisonment, decides to dig a tunnel to escape. He works for many months on this tunnel, and finally finishes it. He decides to break out during the day, figuring the guards will not suspect this. As he breaks through the ground to the surface, he finds himself in a preschool playground.
He is surprised, but he rejoices anyway, shouting, “I’m free, I’m free!”
At this a little girl approaches him, puts her hand on her hip, and says, “big deal! I’m four!”
