That popping sound

I just figured out what that strange sound is. Have you heard it too?
It's this sucking - popping sound, almost like the plunger coming up out of the toilet.
George Bush's approval rating is sinking. More and more people are sorry they voted for him.
Some have even come to realize that he is lying scum.
I think it's the noise made when people pull thier head out of their ass.
