Pizza boy Doug woke. Scratched his crotch and headed to the john. He felt his stomach rumble, as he sat down on the commode. He cut loose a massive fart, and then pushed hard. He felt himself draining from his young body. Water rippled below him, and he fell. Cold water enveloped him. Doug thought, "Oh, crap!" as he realized what had followed digestion, and apparently possession was 9/10ths of the law. He had to warn Matt-Doug, but how?
Light spilled in, as the Pizza boy stood and wiped his ass. The last thing he remembered was eating a slice of happy face pizza. It must have been laced with drugs. Out of habit, he flushed. Turd Doug suddenly wondered what happened to sewage. A vision of Southpark's Mr. Hanky flitted through his fading mind. Yes, feces were made of living microorganisms, which died when they left the body. The cold water must have hurried the deaths of quite a few. He willed a message to Matthew-Doug "Don't go to the bathroom!"
Matthew-Doug woke and scratched himself. Doug-Matthew his new bitch lay sobbing into the pillow next to him. Matthew-Doug smiled and headed to the toilet.
Pizza boy still hadn't been paid, so he headed to the kitchen to try to find some cash. Instead he found a slice of pizza in a cupboard. He took a bite, and Doug was the Pizza Boy again. His neural link to Mr.Hanky-Doug was intact, so he immediately ran to find Matt-Doug to stop him from using the toilet.
Doug-Matt opened the locked door to admit Pizzaboy Doug, a loud flush sounded from the bathroom as Doug-Matt started to quiver. As Pizzaboy-Doug watched, Doug-Matt collapsed into a hideous pile of protoplasm.
"I'm me again!" shouted a joyful Matt from the bathroom.
Pizzaboy-Doug looked at the half slice of pizza still in his hand, and smiled.
