During a study session for our final exams, a fellow grad student said that she thought that our math professor had been working on the final iteself when she had stopped by for last minute help during his office hours, mostly because he closed a text editor window right after she came into the room. Another in the group quipped that maybe he was working on his latest Harlequin romance novel.
"God, I hope not." she responded. "He was writing it in LaTeX."
