In university, I had this eccentric lecturer who'd repeat, almost manically, "Software Maintenance is the worst. Whatever you do, don't work for the maintenance department.". Every lesson. EVERY LESSON!
One of my slacker friends, who barely attended class, was once caught daydreaming. "Slacker, I've never seen you in class before. Do you take this course?". Without missing a beat, this guy says "Maintenance department".
(I just fixed a rather infuriating bug today and was reminded of this story.)
