Jim Davis's motive in drawing this sketch was clearly masturbation. He was embarrassed to keep pornography in his home with the sentiments of the time and had to draw his own material. Ass appreciation was dangerous in pre-Mix-a-lot days, zoomers have no idea. My thought is that he drew this with the intent I just described, then realized he had a deadline coming up in minutes. He started a decent joke but as the deadline neared, he just threw words into the caption, checked his pants for stains, and sent it to the presses.
