Many mathematics titles (not to mention the names for notions) like to involve a game of double meanings, repetition, wit, connotations, seeming absurdity, self-referencing, self-mockery and the like. I propose creating list of some known examples of such titles in areas of our interest. Maybe I should have titled this page Title of titles to keep the spirit on.
In that vein, I just introduced the term ‘punny’, although it is a cliché.

Several more candidates of similar character are listed in the responses to MO question most-memorable-titles. See also MathOverflow parodies-of-abstruse-mathematical-writing.
