After looking through it, he falls into the tunnel of life. At school, during a biology lesson, a fight breaks out between the boys because of Andżela. They end up on the carpet at the headmistress Frał's, who is, by the way, the class teacher. As a punishment, the teacher makes the boys mop the hallway, and lets Anusiak take the girl home. The boys are distracted from their work by some noise coming from the hygienist's office...
