Yes, John Oliver sat down with Edward Snowden in Russia to talk about dick pics (among other topics), but even if that moment seemed farcical, it's actually very educational in that it guides people through the functions of various surveillance programs within the (presumably) relatable context of sending photos of your genitals over the internet.
Consider, then, the website Can They See My Dick as aptly titled further reading. Created by Olivier Lacan in appreciation of the interview, Can They See My Dick lays out how programs like Section 702 ("one-end foreign dick"), Executive Order 12333 ("dick smuggling"), and Section 215 ("dick metadata") actually work with respect to... yeah, you guessed it. It's also just as amazing that this URL was available.
Turns out, there’s a lot of people wondering if the government can see their dick. Who knew? http://t.co/zsTNgvjEvv— Olivier Lacan (@olivierlacan) April 6, 2015
That's the subversive beauty of the Oliver / Snowden segment in the first place. Yes, it's one long dick joke — but it's a dick joke that actually teaches you something important.
