My elective courses are chosen almost entirely by which books I can pirate. At the beginning of the semester, I fire up uTorrent, and start browsing around. If I can find the text book a course uses, then BAM, I'm taking that course.

It's the only thing I pirate these days, and I know its wrong, but I would be lying if I said it didn't feel like victory.

A course requiring 4 books, and using only 1/10th of each one is beyond frustrating.
