For a quick chuckle, read this. Not a joke, cuz this really happened; "Teacher and Student"

Both were inside the car that was being used for Drivers' Training, as offered by the school district.

Teacher said something about the sandals the student was wearing, indicating that shoes are safer. "Thongs are not good to wear while driving," calmly stated.

The Reply, "How do YOU know what underwear I have on??!!"
