Happy Monkey is any moment that you feel the burdens lifted, that you feel a lightening of the mood, that you feel puckish and prankish and like kicking your heels.

An alternate personal greeting of the Christmas Holiday Season for atheists. It originated on December 18, 2008 on the science blog, Pharyngula. The blogger, PZ Myers, received an email in which the writer referred to evolutionists and atheists as worshiping Charles Darwin as a god, and proceeded to say, "Until then, happy monkey! (or what ever non Christmas evolution people say)".
We wish you a Happy Monkey, and a Happy New Year.
