Lunar Whatsit

Here are the eight phases of the moon (for those of you who like trivia):

New Moon (the boring one)
Waxing Crescent (the one which, as a child, I called a fingernail)
First Quarter (also known as a waxing quarter)
Waxing Gibbous (the overlooked one)
Full Moon (the one you don't want to stargaze - or hide in the woods - under)
Waning Gibbous (similarly overlooked)
Last Quarter (also known as a waning quarter)
Waning Crescent (another fingernail)
