Hillary Clinton got unusually riled up at a rally in Reno, Nevada, today. So much so that she barked like a dog. The unexpected moment occurred while Clinton was telling a story about fact-checking Republicans, whom she accused of twisting the truth about the Great Recession. Clinton explained that it reminded her of an old radio ad she liked in Arkansas where a dog would bark every time a candidate said something that wasn’t true. Clinton went on to say that she wished every time Republicans said things like, "'Oh, the Great Recession was caused by too much regulation,'" she had a dog to bark at them. And that's when the dog impression occurred. "Arh, arh, arh, arh!" she said in a high-pitched tone. "You know?"
