Top 10 Things You Didn't Know About Thanksgiving

The annual White House tradition of pardoning a turkey before Thanksgiving began in 1947, when President Harry Truman took pity on one lucky fowl. Other historians say the practice began during the 1860s, when Abraham Lincoln granted a pardon to a pet turkey belonging to his son, Tad. The tradition may alleviate some of America's guilt, but it doesn't stop us from slaughtering more than 46 million turkeys for the holiday. Even so, as Alaska Governor Sarah Palin proved during a recent interview in her hometown, Americans prefer public acts of mercy to massacres.
