Ninja

"Great," said the ninja. "Let's get started." Bob had never before thought that his black-belt in karate would ever come in handy. Bob started using his ninja skills on the ninja. After a few minutes Bob realized that he was fighting by himself. Charlie had gotten scared and had hidden in the bushes.
"Scardy cat," Bob mumbled.
Finally the ninja panted, "Fine! I give up! You win. You both may pass." The ninja then stepped aside. So Bob and Charlie walked past the ninja and continued their way.
