Q:	How many gradual (sorry, that's supposed to be "graduate") students
	does it take to screw in a light bulb?
A:	"I'm afraid we don't know, but make my stipend tax-free, give my
	advisor a $30,000 grant of the taxpayer's money, and I'm sure he
	can tell me how to do the gruntwork for him so he can take the
	credit for answering this incredibly vital question."
