You're right, that was the NSA. I'm the director of the NSA, and because of your conspiracy theories, I have sent my minions to spy on you and find out all your dirty secrets, so that when we stage a terrorist attack we can take you out quick, before you let anyone know 'the truth'. Osama and the reptilians are also in my employ. (What a great band name: Osama and the Reptilians!)
