WASHINGTON, DC—Upon injuring a toe Sunday, Corey Flintoff, newscaster for NPR's All Things Considered, unleashed a string of rich, pleasantly modulated obscenities. "God fucking dammit," Flintoff warmly intoned after dropping a heavy-duty router on his foot while working in his garage. "Stupid fucking cocksucking son of a bitch." Added Flintoff in a lush baritone: "Goddamn motherfucking shit-for-brains. This is NPR." Next-door neighbor Cheryl Thomas, who overheard the tirade, said Flintoff's delivery was so melodic, she was unaware that he was swearing.
