GamesRadar - War. What is it good for? Funny pictures, that's what. Mind you, we're not talking about real war (which is decidedly unfunny), but rather the make-believe gaming kind where we get to shoot friends and strangers in the face online and then head off to sleep in our cozy, murder-free beds. And of all the video game wars we've enlisted in over the past decades, few come close to the meme-friendly pedigree of the Call of Duty franchise.
