Apropos this, cribbed from the GNU Emacs manual by (originally) Richard Stallman:

35.6 Mail Amusements
====================

`M-x spook’ adds a line of randomly chosen keywords to an outgoing mail
message. The keywords are chosen from a list of words that suggest you
are discussing something subversive.

The idea behind this feature is the suspicion that the NSA(1) and
other intelligence agencies snoop on all electronic mail messages that
contain keywords suggesting they might find them interesting. (The
agencies say that they don’t, but that’s what they _would_ say.) The
idea is that if lots of people add suspicious words to their messages,
the agencies will get so busy with spurious input that they will have
to give up reading it all. Whether or not this is true, it at least
amuses some people.

You can use the `fortune’ program to put a “fortune cookie” message
into outgoing mail. To do this, add `fortune-to-signature’ to
`mail-setup-hook’:

(add-hook ‘mail-setup-hook ‘fortune-to-signature)

You will probably need to set the variable `fortune-file’ before using
this.
