You could hum the Angry Birds theme song in the subway and someone would look up and smile at you. It's become that popular.
The game is very simple. The pigs stole the birds' eggs. The birds are angry. The pigs build forts. The birds jump into a sling shot where you aim them at the fort. When a bird or a bit of debris hits a pig, he explodes. Your mission is to kill all the pigs. And the pigs don't seem to mind. They're happy, snorting and grinning, all the way up to their moment of death. That's the gist of the game, though it has a few little subtleties. No spoilers. ">
Another thought hit me. When the elaborate pig forts topple it kind of looks like the Twin Towers coming down on 9/11. And the birds, well they're a lot like a suicide bombers. Well, actually they are totally like suicide bombers.
