Jack

If I were Jack Bauer I could say the following and mean it:

"You probably don't think I can force this towel down your throat, but trust me, I can. All the way."

"I have killed two people since midnight. I haven't slept in over 24 hours. So maybe you should be a little more afraid of me than you are now."

"The only reason you're conscious right now is because I don't want to carry you."
