"I'd like a STANDARD BRIEFING."
"I have flight service information _ _ _ _ _ _ _ _ _ _ _ _."
They will ask you for the information on the FAA7233-1 form, pretty much in the order it appears.
Later get an ABBREVIATED BRIEFING, to see if conditions have changed (or earlier an OUTLOOK BRIEFING if deparure time is 6 or more hours away).
"Yes, Sir, Thank you, Sir." -- your conversation is being recorded!
