One of the main reasons Jack Bauer is a bad-ass is his ability to dispatch terrorists though a variety of ways, whether its as simple as shooting them or getting creative and taking them out with a fire axe. However, there is such a thing as being too talented with your killing. At the beginning of season 6 Jack was taken by Abu Fayed, who agreed to reveal where Hamri Al-Assad - the suspected terrorist leader - was, in exchange for Jack. However during Jacks torture session Fayed revealed that he was the true mastermind of these attacks. Determined to tell CTU whats really going on, Jack pretends to flatline while Fayed is out of the room. Getting the guard to come up close, he bites down on the mans neck and tears out a chunk of his neck. Jack escaped and was able to save Assad from being killed, but that doesnt negate the fact that channeling his inner vampire was really disgusting for network TV. Television may be a lot more violent these days, but that sort of gruesomeness belongs on Game of Thrones.
