Son, you'd better put that down, or you're gonna get hurt.

You have no idea how far I'm willing to go to acquire your cooperation.

Michael Amador: You betrayed me, Jack, you were CTU all along.
Jack Bauer: That's right, Amador. You betrayed me, too, I'm just better at it than you.

I'm gonna need a hacksaw.

The only way you're going to die is if I kill you. Your bomb's not going off.

[to Joseph Prado, after breaking every finger in his hand] This will help you with the pain. [knocks him unconscious]

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

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

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.

I don't have time for this.

When I'm finished with you, you're gonna wish that you felt this good again.

You don't want to try me on that one.

If you don't tell me what I want to know, then it'll just be a question of how much you want it to hurt.

Trust me, you don't want to go down that road with me.

"There's a running joke among fans that Jack never goes to the bathroom. We had a scene where I was running towards a sign pointing 'BATHROOM' to the left and 'OFFICES' to the right. I did a double-take and ran towards the bathroom! We sent it in to the network, as a joke reel. But, quite frankly, nobody wants to see Jack Bauer go to the bathroom."
