In Washington, there was a sportscaster named Ken Beatrice, for many years at WMAL, then at WTEM. One night, he was talking to his producer and thought they had already gone to break.
Not realizing the mic was still live, he said, “That caller was a f——ng moron.” He got suspended for a week.
Years ago we had a local TV sportscaster in Pittsburgh who got fired for opening a report on the Pirates with “What a sh*tty way to lose a game!”
