Angry Birds

What is it about that game that is soooooo addicting?  I am hooked.  It is really a simple game but I just cant seem to stop playing.
For those of you who aren't familiar with the game here is how it works.  Pigs capture or eggnap the eggs of these angry birds, who I can only assume were quite docile until their offspring were eggnapped.  That's the back ground like I said simple. 
There are different types of angry birds that you shoot out of a large sling shot at the pig strongholds.  Some birds pulverize glass, others punch right through wood, some drop explosive eggs, while others are like a bomb, they explode.  The object of the game is to eliminate all the pigs in the level with your set number of birds.  After you have cleared all the levels those angry birds are reunited with their eggs. 
Why didn't the pigs just have a big breakfast?  I don't know.  I mean they are pigs right?  And as far as I know pigs eat most anything, and eat a lot of it.  So they missed a golden opportunity for a nice big breakfast, but I suppose being pigs they probably aren't the sharpest tools in the shed, and perhaps that is why they didn't just eat the eggs.  I guess we will never know.  Some mysteries of the universe are never meant to be discovered.

Any way for those of you who arent snoring and or drooling by now, and like games to occupy your time when you have little else to do, I would recommend angry birds.
That is all
