1439: catch 22 Nov 19, 2018

Sometimes, a pop-culture reference will make its way into common parlance. With the word 'catch 22'—which grammatically is not two words when used as such—can refer to a paradoxical situation or logical fallacies depending upon the idea at hand. It comes from the title of a 1961 book in which the main character pretends to be insane to avoid combat, but his actions are taken to prove his sanity. However, it is possible that many of the people who would use this phrase have not read the book, as now the reference is no longer just a reference, and can exist in its own right.
