Jesus..
Man, you people just don't understand. I draw a lot, but not on a computer. Do you realize how fucking hard it is to just draw on paper?!
You don't need a damned plot when your artwork is going to be the attraction for your work. I admit, a plot is a plus, but it's not needed every time. Learn to draw, and you'll understand why some of the nicest looking animation has very little humor and plot to it.
