some girls in his class took this as a challenge and tried to persuade him to have sex with them.
I would imagine the script really looked something like this...
Olaf's parents: Olaf, when was the last time you intentionally brought attention to yourself at school so you could give a Witness to your classmates?
Olaf: I will do it today!
Scene - Olaf is in class with fellow students and teacher. Students and teacher are paying no attention to Olaf as he has intentionally rejected any attempts by fellow students to engage in conversation.
Olaf: I have never had sex and none of you can make me no matter how hard you try!!!
Girl Student: You mean you would turn down sex if it were freely offered to you, Olaf?
Olaf: Get away from me you Jezebel!
Later that day at the home of Olaf.
Scene - Olaf is having dinner with his parents.
Olaf: Mom. Dad. Today I gave a fine Witness. A girl tried to tempt me with an offer of sex, but I let the class know that I am one of Jehovah's Witnesses and I won't commit fornication.
Parents: Well done, Olaf!
