A brand new school opens is freshly painted doors to welcome its first students to their first classes.
An enthusiastic history teacher, Anne Akronism, arrives to face her first students in her first class ever.
In her defence, she considers that she is not simply teaching history, but helping to make history.
She arrives to find three adolescent boys sitting in a row, all have their heads bowed down, each is reading a book.
She is a bit surprised to observe that the covers of the three books are exactly the same.
"Morning boys," says the teacher. "Enjoying your book?"
"Yes Ma'am" the three say in unison as they look up.
She gasps. The three boys are dressed quite differently - one has tattoos on his arm, the one next to him has a prominent crucifix around his neck, and the third is dressed in a neat-preppy way - but the three appear to be physically identical: same eyes, same nose, same hair, same height, same build.
