Okay people, I guess you are stumped. I am going out of town for a few days and won't be available to check this, so I'm going to give the answer.
It's from the first scene of First Contact, just after Picard has woken from his nightmare about the Borg. An admiral calls, and says, "Did I catch you at a bad time, Jean Luc?" and Picard replies, "No, of course not."
Somebody else throw out a new quote. Peace out!
