Department spokesman Cpt. Mark Hoffman said Saturday that he's gotten calls about the video from media outlets in Australia, England, Germany, and throughout the U.S. It has 380,000 YouTube views.
Hoffman says Davis, a 19-year veteran of the department, is "the class clown" and loved making the video. He says the 48-year-old father of four knows "Shake it Off" so well because of his 10-year-old daughter.
