I have some more quotable quotes from HF that make me roll my eyes, but smile when he says them anyway. I don't know if he's actually used them on people while working, but I like to think he does. And I like to imagine that he says it like Chuck Norris would in Walker, Texas Ranger.
"You can say what you want, but you are going to do what I say"
"You can have the last word, but I get the last act."
and my personal favorite from ALIAS season 5:
(Jack Bristow watching agent Tom Grace at the firing range.)
Jack: I think you got him.
Tom: My mother always said, if somebody was worth shootin' once, they're worth shootin' twice.
Jack: I'm sorry I never met her. She sounds like my kind of woman.
