Country Rock

Yesterday's Lab test ended with the following question:
Explain the definition of country rock in your lab manual. (2 points)

We both had really dumb answers:
Me: "A rock not regularly found & disturbed, which therefore is in its original & natural environment."
Neil: "A country rock is a rock that formed long ago & was also expelled & into the surface thousands of years ago. It is smooth from erosion & probably has moss growing on it. AKA rockabilly."

Needless to say, we both received zero points for our very well thought-out responses.

Oh, and there WAS no halite on the test. Therefore, Neil's licking it was not necessary, his illness could have been evaded, and my hesitancy proved victorious once again. Muahahahaa. Goodbye.
