Pearle “Math Class” [00:30]# Students during a math class. The looks they give the goings on at blackboard, where the teacher is demonstrating some complicated algebraic equation, range from incredulous and blank to downright catatonic. One student is so bored that he keels over and breaks his glasses. If he had bought his glasses at Pearle’s he would get them repaired free, for they replace broken glasses even if the owner broke them himself.
