This is a video guide showing how to get the "Say Hi to the Internet" Achievement in Far Cry 3. Note that the actual location of the head is at X: 620.5, Y: 557.7.
Check out The Far Cry Experience and see the background of this easter egg for yourself at: http://www.youtube.com/show/thefarcryexperience
This tie-in to the "Far Cry Experience" video series from Machinima shows actor Christopher Mintz-Plasse (of McLovin fame) in a very unfortunate situation.
Travel to the map coordinates above to see his fate. In the fourth episode of the video series, viewers could vote whether Christopher lives or dies after being captured and dug neck-deep in sand.
Travel to the south-eastern edge of North Rook Island, and liberate the Broken Neck Home outpost. Next, grab a boat or walk northwest up the beach.
Keep going until you find a tree with several quite-dead people hanging from the branches. Look on the beach itself for a glowing head at the map coordinates: X: 620.5, Y: 557.7 — just interact with it, and you'll unlock an achievement.
