-Bertrand Russell and Alfred North Whitehead co-wrote the ''Principia Mathematica'', with the intention of cataloging all of mathematics and ridding it of contradiction and self-reference. Kurt Gödel later showed that such a system is impossible, and that any system of axioms (like mathematics) is incomplete.
+{{w|Bertrand Russell}} and {{w|Alfred North Whitehead}} co-wrote the ''{{w|Principia Mathematica}}'', with the intention of cataloging all of mathematics and ridding it of contradiction and self-reference. {{w|Kurt Gödel}} later showed that such a system is impossible, and that {{w|Gödel's incompleteness theorems|any system of axioms (like mathematics) is incomplete}}.
 Here, Russel and Whitehead are perusing a more salacious, but no less comprehensive, task: compiling a list of all sexual fetishes. When Gödel says he likes "anything not on your list," Russel and Whitehead have no way to complete their list. Whatever they leave off should be on the list, as long as it's off the list. This paradox is essentially the same as the one that doomed the ''Principia''.
-In the title text, Georg Cantor is the inventor of set theory. If you have a fetish for doing everything in the book twice, than that belongs in the book, which you then have to do once more, which adds another item to the book ''ad infinitum''. Russel and Whitehead finally acknowledge their defeat.

-There are two possible references here. One is from the book ''{{w|Contact (novel)|Contact}}'' by Carl Sagan, where the existence of God was shown in the last chapter to be encoded in the digits of {{w|pi}}. The other is an old joke of a {{w|fortune cookie}} with a fortune that reads "Help! I'm trapped in a fortune cookie factory!"
