Their son liked to play in the woods as a child and for the Darling family they did not see anything wrong with that. But they had made one critical error in their thinking and that was they had never thought about what their son was actually doing in the woods. They had wrongly assumed that he was merely roaming and wandering, trying to acquaint himself with the countryside which they thought to be normal for a pre-teen child. But when their son, Carl, had arrived into his teen years and he was still heading out to the bush they started to wonder about their son, thinking that he had become estranged from people. There were certain anti-social behaviours that he had developed that were of a malevolent nature. As he aged he began to talk back to his parents, using a series of curse words that shocked them. When they tried to talk to him he would not listen and simply leave the house and hide out in the woods.
Then one day the father of Carl decided that he was going to dress up in camouflage and follow his son into the bush. Upon surveillance the father realized that his son was simply watching the wildlife, but had seemed to have taken a liking to wolves, something that didn't concern him.
For the next year on every full moon night Carl would leave the house at night and not come back until the morning. At this point in Carl's life he had dropped out of school, but his parents realized that their boy was extremely intelligent as he read and wrote voraciously during the day.
But strangely by his fourteenth birthday Carl was able to grow a full beard and would shave two times a day. One day he came out of the shower and had no shirt on and his parents were appalled by the frightening amount of hair he had on his back and chest. This was something that was not normal for a boy of his age. They also noticed that he had a bite mark on his stomach that they had never seen before, and they knew it was not from a dog but from a much bigger beast. When they asked him about it he said that it was none of their business.
Carl's parents talked it over and the evidence in front of them was undeniable: the excessive body hair, shaving twice a day, the nasty bite mark and Carl being mesmerized by the full moon. They believed their son had become a werewolf. Somehow they were able to convince him to go see a doctor where they asked the physician to analyze his blood for anything abnormally inhuman.
When the tests came back the doctor told Carl and his family that he was normal and bite the mark was from a bigger dog. He was negative for rabies and his excessive body hair was because of puberty.
Carl turned to the doctor and said, "Can you explain this?"
Carl quickly whipped down his pants to pull back a forest of pubic hair from his leg which revealed a gigantic 18 inch penis, something that the doctor thought was originally part of his leg.
The doctor was speechless. Carl's mother passed out and his father couldn't stop staring.
