This is a story about a housewife who has an idea for "computer skirts" and decides to act on it. It is a ridiculous idea, bordering on absurd, but somehow she is able to manufacture and market these cotton elastic banded skirts to slide down around a computer monitor so that it looks as if it is wearing a skirt.
The narrator can't really believe it and then laments the various times he missed out on opportunities. Is it being afraid to get embarrassed that holds the narrator back or is it sheer skepticism and lack of insight? Regardless, he seems to be on the lookout for the next big thing as the story concludes but as a reader, you get the sense that he won't find it.
It's as if the next big thing will never be something you are actually looking for! The next big thing will simply happen to a person, a whim put into action. This narrator is thinking too hard.
