Ross hates his boss

Ross's boss was constantly sending him on errands that were not part of his job description, such as going to his house to pick up his dry cleaning or washing his car, etc. It was driving him crazy. On top of that he stole Ross's girlfriend, or rather future potential girlfriend, right out from under him. And his boss, Carl, treated her like shit. He was covinced that he beat her as well.
Ross stole the collar from his boss's neighbor's dog and used his dreaded spare key to sneak into Carl's house.
He crept up the stairs and heard Carl's snoring. He entered the room and rolled the medallion out of the box onto the bed. Then he watched as it slid towards Carl's face. At the same time he dropped the collar where it would touch. Ross held back laughter as long as he could as he watched the sleeping man turn into a dog. By the time he was laughing it was too late to stop the change and Carl woke up. Carl stumbled around confused. Ross grabbed him by the scruff of his neck and pushed him out the door.
Ross laughed hard and long and went into his boss's living room to watch his big screen tv.
