A few years ago, a student raised his hand with a question about the deadline for submitting final papers in my senior seminar class. "Now, is the paper due midnight East Coast time or midnight West Coast time?" he asked earnestly.
I responded that if he provided proof he was on the West Coast, I'd happily accept papers until midnight Pacific time — I wasn't planning to stay up late to watch the essays roll in either way. That set off a full week of students photoshopping their faces onto images of California beaches and Disneyland. In the end, every student submitted their paper on time.
