1. December 9, 2009 BReading Ch. 15 (Cenozoic History) BFinal Exam date: TU, Dec. 15 Material covered: Ch. 13, 14, 15, 16(?) + movie Firefighters rescue boy with tongue stuck to post BOISE, Idaho — It’s become an annual winter tale: A young boy gets his tongue stuck to a metal pole, perhaps as the result of a dare. This year, the scene straight out of the movie “A Christmas Story” unfolded Tuesday morning in Boise with a boy of about 10. Boise firefighters used a glass of warm water to free the unidentified boy from the metal fence pole, according to the Idaho Statesman newspaper. Fire Capt. Bill Tinsley says the boy’s tongue was bleeding a little, but he was OK and allowed to continue walking to school. Rescue workers responded after a woman driving by saw the boy and called police dispatchers. Last year, the unlucky boy was a 10-year-old from Hammond, Indiana — especially apt, since the 1983 movie is set in a fictional city based on Hammond.
