Little Bobby always wanted to own a Hercules bicycle, so when his dad bought him one, Bobby was overjoyed. He spent most of his summer vacations riding his brand new bike, ringing the bicycle's bell and waving at all the jealous kids in the neighborhood. One day, some bullies in the locality stopped him, then drew a circle in the dirt road and told him, "Stay inside this circle. If you step out, you will get the thrashing of your life."
Then they picked up some iron rods and started hitting his new Hercules bicycle with the rods. When they were finished busting the bicycle, they looked back at Little Bobby and saw him smiling. They hit the bicycle some more, and he was still smiling. They walked up to him and asked, "Why the grin on your face? Don't you realize we smashed your new bike!"
Bobby said, "I know, but you never noticed I stepped out of the circle 12 times."
