I am suddenly nostalgic for the Googlewhack fad: https://en.wikipedia.org/wiki/Googlewhack

"A Googlewhack is a contest for finding a Google search query consisting of exactly two words without quotation marks that returns exactly one hit. A Googlewhack must consist of two actual words found in a dictionary.

Published googlewhacks are short-lived, since when published to a web site, the new number of hits will become at least two, one to the original hit found, and one to the publishing site."
