The doctor walks in and says, "Please repeat for me what your condition is, because I'm having trouble believing what the nurse wrote down."

The man grabs his wife's hand and looks down with a mix of sorrow and shame. "Well, doc, every time the misses and I make love...uh... everyone in the family gets sick. Even my children who are in their own rooms at the time."

The doctor stares at them, perplexed and a bit concerned that this is some kind of abuse case, "You're kidding me, right? Well surely this is impossible."

"Well, doc, I suppose we could demonstrate if you don't believe us. Anything to get to the bottom of this mystery illness. Our kids are in the waiting room." the man explains.

The doctor calls the nurse in and instructs her to bring the kids into their own separate rooms.

"Okay, sir, we have your children in nearby rooms. We'll give you some privacy and observe them while the.... erm... test is being performed. Just let us know when you're done."

The doctor shuts the door and gives the nurse a concerned look as they both go to monitor the children.

A few minutes pass and suddenly the boy looks pale and ill. He leans over from the bed and begins to vomit.

At the same time the young girl starts defecating in the bed and crying.

Shortly after, the boy starts defecating as well. Horrible, green, liquid diarrhea floods onto the floor, mixing with the vomit.

The two children then seem to go into a psychotic episode. They both seem entranced as they climb down to the floor and start playing in the feces and vomit in their respective room, pawing through it, smearing it on their faces like war paint, patting into their hair.

The doctor panics and runs to get the parents.

The nurse and doctor storm into the exam room to find the two adults mid coitus, similarly covered in feces and vomit, passionately making love.

The two lovers shriek and disengage from the act, turning to face the doctor and nurse, seemingly confused and shocked.

The doctor shouts, "I HAVE NEVER IN MY LIFE SEEN ANYTHING LIKE THIS, MISTER AND MISSES ARISTOCRAT!"
