Oh Noes! You've got the blues. Whether it's because your kitty died or you realize that the world will INDEED end in 2012, you're in dire need of some cheering up. Your friends/family/significant other are all too busy for you, so it looks like you'll just have to go solo on your mission to turn your frown upside down.
This whole situation boils down to the essential question:
What is the one thing that can always always cheer you up?
When I feel down, I let 54 parakeets, or some other kind of small exotic bird, but always in groups of 54, loose in my house and fire a nail gun at them, trying to stick them on the walls. Even if I can't, the chaos still lifts my spirits. There's something about the colors and the impending doom of creatures smaller than me that makes me feel almost godlike.
Sometimes I wonder if, for God, everyday is like firing a nail gun at small, colorful birds scared shitless by the knowledge of certain death... but I digress.
