One morning Johnny is early for school so he goes into the classroom and
writes on the chalkboard, "Johnny has the biggest dick in school" in huge
letters, then runs out of the school building giggling to himself. After the
tardy bell rings, he calmly walks into the classroom with the teacher. The
teacher reads it and then tells some students to erase the board. Then the
teacher tell him she wants to see him after school.
So after school Johnny and his buddies go back to school. Johnny tells his
buddies to wait outside. About an hour later he walks out of the school. And his
friends eagerly ask him what happened. With a lazy smile, he says, "Well,
it pays to advertise!!"
