Yesterday, a math professor at Michigan State University was teaching a freshman calculus class when he suddenly had some kind of NERVOUS BREAKDOWN. According to students in the class, he started screaming and swearing . . . and then STRIPPED NAKED. Then he ran into the hallway, and kept screaming and ranting about everything from religion to Steve Jobs. It took the campus police about 15 minutes to get there. From a photo that a student took in the hallway, it appears the cops cuffed him so they could take him to the hospital for evaluation. He was not charged with a crime.
