Rock Identification
(imgs.xkcd.com)
'Is it worth anything?' 'I dunno, is the answer to that question worth another $5?'
At the small college I attended, Geology 101 was known as "Rocks for Jocks" because it was the class jocks took to satisfy their science requirement. In one hallway was a big display board with a bunch of labeled rock samples on it. If you memorized all of them well enough to identify them on the final, you were almost guaranteed to pass. So there were always football jocks standing there studying that board.
Yeah! Science!
