A friend of mine told me that there was a disease called 12 Year Penis Syndrome, and it made it so that when an afflicted girl turned twelve she would grow a penis and turn into a man. I believed this for a while, until I was 15 and brought it up in biology class. Needless to say, the teacher was pretty amused that I believed it
