A math teacher in Allons, Tenn., may lose his job after he wrote on a student's forehead.
Alex Boles is accused of writing the word 'stupid' on a student's forehead because that student didn't understand a two-hour math lesson.
School officials say they were shocked to hear of the incident.
Boles says it was all in fun, but he has been suspended and may be fired after an investigation. He also faces possible assault charges.
