Quines

A Quine is a 'self-producing' program; i.e. a program whose output is its own source code. For example, here's a quine written in Ruby:

printf(s = 'printf(s = %c%s%c, 39, s, 39)', 39, s, 39)

For a terrific discussion of quines, see the David Madore Quine's page. If that page is unavailable you can get a zipped copy of it here.
