An astronomy professor at Keck was about to give back our midterms. The class is large (upwards of 60 students), so the professor had all of the tests on his desk and asked us to come up and take our tests in a civilized manner. To make this point he said, "THIS ISN'T MECCA! DON'T STAMPEDE!" This was precisely two days after over 700 pilgrims were killed in a stampede in Mecca.
