Why is my son so weird?

my son has been very weird lately i found a GQ magazine that has glee cast in it my son loves the show anyway i opened it and the girls all were scratched out and there were pink hearts all over that other tall guys head and yesterday his friend john came to our house they told me they were studying science when i went to his room to bring them some soda i found them shirtless and they told me it was all about biology is my son too obsesed with glee or were they really studying?
