I think even "I said you might want to!" is too much. It smacks of a shoddy American sitcom where they say these non-jokes to cue the canned laughter. If they insist on having four panels, they could have a third panel with the two going through some security rigmarole, maybe stick in a few subtle visual jokes.
shift 1,2,3 to 2,3,4 and have 1 as an establishing shot of the nsa hq to make the setup clearer. right now it's like you see the punchline, then an extra panel, then go back to see what was the big deal and realize somewhere in the background it says nsa hq.
