Comedy is grievances. It's a recitation of grievances - whether they're inconsequential, superficial - like "my wife shops too much", or "kids today", all those old-fashioned themes - or, if it's deeper, and somewhat more thoughtful, about social imbalance and inequities, and the folly of human behavior. It's usually a complaint.
George CarlinThe fact that I didn't finish school left me with a lifelong need to prove that I'm smart, prove it to myself, maybe to the world. I [also] needed to be - not the center of attention - but I needed to be able to attract attention when I wanted it, through my stunts and my fooling around physically with faces or postures or voices I would do. Those things are important elements in the drive behind all of this [my career].
