Zack and Cody were playing tag in the lobby when Mr. Moseby grabbed both boys from the collars of their shirts.

"How many times do I have to tell you to stop running in the lobby?"

Both kids said they were sorry and headed over to the game room. There, Zack went over to his favorite game and saw something that amazed him. Someone had beaten his top score. That has never happened. Right above where it said, ZM, it showed JMK.

"Who's JMK?"

"I believe that's me," said a voice from behind them.
