The Way of the Ninja

You decide to go back to sleep for a little while longer. You wake up six hours later and realize you slept through graduation. You cuss to yourself, as a knock on the door is heard. Grumbling to yourself you get up and walk over to the door. You open the door to see nobody there.

"oh shi---" *BOOOOOOOOOOM!!!!* Your last thought as you die is "The life of a ninja is hard..."
