Inspired by an email PZ received, which ended:
- Until then, happy monkey! (or what ever non Christmas evolution people say)
- P.S. MERRY CHRISTMAS! (It's about calling it what it is!)
Usage note: Happy Monkey is uttered without articles (a, an, the). Incorrect: "Have a Happy Monkey, everyone!" Correct: "Happy Monkey everybody!" Presumably it does not refer to any particular primate, but rather the general cognitive state of being gleeful and monkey-like.
