An internal agency memo noted that among British analysts shown a presentation on the NSA's progress: "Those not already briefed were gobsmacked!"
Those British analysts really dig deep when they head on out to do their analysing. As shown above, they've uncovered (no pun intended, as you'll see if a bit) the NSA gobsmacking (whatever that means, but it sounds like fun) individuals sans underwear.
On second thought, I don't think I would want anybody gobsmacking me donning or sans briefs or boxers.
