Rocks and Minerals Question Marathon

Postby Jim_R » October 11th, 2012, 6:19 am

This thread is for asking and answering practice questions about Rocks and Minerals.
-The path of the Administrator is beset on all sides by the inequities of the selfish and the tyranny of evil men.

-Nothing\'s gonna get deleted. We\'re gonna be like three little Fonzies here. And what\'s Fonzie like? Come on, what\'s Fonzie like?
-Cool?
-Correctamundo. And that\'s what we\'re gonna be. We\'re gonna be cool. Now, I\'m gonna count to three, and when I count three, you let go of your mouse, and back away from the keyboard. But when you do it, you do it cool. Ready? One... two... three.
