This ghost video is actually a critical examination of the TAPS Ghost Hunters Live TV ghostly coat collar yank which aired October, 2008.  In our opinion, the collar-pull (or collar-yank) was contrived and rigged.  Grant Wilson's hand goes under the bottom of his coat and his arm remains stiff the entire time, as if pulling a string inside a rigged coat.  To see how easy it is to do this trick, see the Coat Collar Yank Re-Creation Video.
