Up All Night

PhD Comics has a panel about all-nighters.

I still pull an all-nighter every now and again, though it's certainly harder than it used to be (and I did a Hell of a lot of these in college). Two fundamental differences between my experiences and the description:

(1) I start my work early rather than at O(11pm).

(2) I want to kill everybody when they get up to start their day rather than to kiss them---especially if they wish me a good morning (and doubly so if they have been blasting country music, which was one of the rites of passage in grad school in applied math at Cornell... shudder).
