Sometimes teenagers say the darndest things

A male substitue was filling in for a high school Social Studies teacher.  One of the classes was a particularly trying group of students with a girl, the ring leader, sitting in the very front of the room.  Upon having enough, he looked at her and tried out a phrase his parents had used successfully on him growing up.  He pointed his finger at her, "Don't try me." he said.  She didn't even blink an eye and responded, "I'd love to." Not thinking he could deal with things like that on a day to day basis, he decided to become an accountant.
