After achieving another milestone in Nebraska history–the first two back-to-back home losses in a row since the Precambrian era–did Bill Callahan celebrate by making a throat-slashing gesture at an official? Watch the video for yourself and decide. Either way, Callahan’s added another brick to his wall of douchbagdom, which includes calling Oklahoma fans “fucking rednecks” in last year’s game, calling fifty passes a game and slowing the ABC afternoon games to a crawl for the past two years, and calling such an inept game in the Super Bowl that Bucs safety John Lynch was heard laughing on the field mikes during the game following Rich Gannon’s fifth pick of the game.
