"Today is a special day for all the boys in the class" said the biology teacher, Miss Ewans "Because you all are participating in an experiment. On every boys' table there is a little drink, please guys, drink it" And it was true, there was a liquid in front of every guy. They drank it, as they trusted their teacher. they knew Miss Ewans for years. They all were 16 years old.
"So, the liquid has an effect on human DNA. Some scientists discovered, that a part of the DNA is very similar to an animal, and it differs for everyone, which animal it is. It is like there is a short animal sequence in human DNA, that make us different. This animal differs for everyone, but there are some easy rules. For example blond guys easily have a little lion, golden retriever, sheep or polar bear DNA, while black haired guys are usually have some black furred animal DNA. The liquid that you just drank brings the animal out of you, turning you into a part animal. The scientists who discovered the liquid now testing its effect on you. They already know some rules, as they tested before on some participants. First of all, the serum has no effect to the girls. They tested on guys of different ages already, and they realised that the younger you are, the more you change. When they tested on a 40 year old man, the man only became a bit hairier, with some animalistic characters, while when they tested on a 25 years old guy, the guy was totally covered in fur, and his face and legs turnd completely into deer face and deer legs. They also realised, that the rate of the change depends on the level of testosteron in subjects body. Now they are testing you, and they are curios about how much a teenager's body change, and how much is it permanent. For example the deer guy turned back to human after one month, though he is still hairier than before. For the next few months, you all will live in a house near to the school. Oh, and one more thing: half of the guys usually turn into gay"
