8. The Situation Room
Pete Souza's shot of President Barack Obama and his top staff huddled in the Situation Room of the White House while getting updates on the mission to kill Osama bin Laden may be the single most iconic photo of the year. That instant-classic status was practically cemented by a meme in which the image was altered to include all sorts of characters from pop culture, or in one memorable take, an entire room of Obamas. Even the most ridiculous versions retain the solemn intensity of the occasion, making the absurd added imagery the visual equivalent of someone cracking a joke to relieve the tension in a very grim moment.
