Olbermann is mentally ill. It has been well publicized that he has been under psychiatric care for some time. He had a Dan Rather-esque hissy-fit/walk-off moment at ESPN several years back. They fired him and MSNBC picked him up out the broadcasting scrap heap for a bargain basement price.
I should have said 'They fired him, SEVERAL YEARS OF UNEMPLOYMENT WENT BY, and MSNBC picked him up...'
That must be why Olberman is known as Mr. Prozac.
