Of people who will read this post, more will know my name than will have heard of John Ashbery.

If all the people of the United States (or, indeed, the world!) were surveyed as to whether they had heard of me or of John Ashbery, the difference between us would be statistically insignificant.

Therefore, I am as well known as John Ashbery.

QED.

Repeat as needed with Billy Collins, Kay Ryan, or whomever. Or make your own post and substitute yourself in for me. The applications are endless.
