Ok- I had to go with that one because, as we all know, "its a classic" -and how much does this rock- you get a cool quote in the SUBJECT of the qftd thread and in the explanation of the subject (Jaws and Buffy respectively for those interested).
Anyhoo- some quotes rock and some quotes rock. This quote rocks:
"Trust me. You don't want to go down this road with me." Jack Bauer interrogating a suspect, 24.
And anyone who knows anything about Jack knows that he's an honest, honest man. Just tell him what he wants to know.
