One day, a boy was walking down a road when a frog called to him, “Boy, if you kiss me, I will turn into a beautiful princess.” The boy picked up the frog, smiled at it, then placed the frog into his pocket.
Later, the frog said, “Boy, if you kiss me and turn me back into a beautiful princess, I will stay with you for a week.” The boy took the frog from his pocket, smiled at it, then put it back into his pocket.
Later, the frog said, “Boy, if you kiss me and turn me back into a beautiful princess, I will do anything you want!” The boy took the frog from his pocket, smiled, and put it back.
Finally, the frog cried, “Boy, what is the matter, I have told you that I am a beautiful princess, and if you kiss me, I will stay with you and do anything you want!” The boy took the frog from his pocket and said, “Look, I am an engineer, I have no time for a girlfriend, but a talking frog is cool!”
