Not that I ever had to *cough**cough*..... - Getting back $3 for a book that you paid $95.95 not 5 months ago, opened it 3 times (exam1, exam2, and final) - Walk in to lecture hall, see everyone with scantrons, walk out of lecture hall. - Say these EXACT words to yourself, "Next semester, I'm going to kick ass. No more screwing around!!" or "It's only the first week of class, I can miss one" and finally, "Oh, I know this. I'll be back in 3 weeks when they're finally teaching something I don't know".
