He's not buying it

My twelve-year-old son Greg is not one to submit to servile conformity. Tonight he told me that this week in science class will be devoted to "sex ed." I asked him what he has learned so far in the first two days. "I learned I have a penis," he replied sarcastically. "I tried to sleep, but I couldn't, because they were playing some loud video about teens choosing not to have sex. I just don't care why they don't want to have sex! As soon as it was over they probably went back to their strip joints!"
