I pulled them fairly frequently in college. My friends and I were all very late night people anyway, usually going to sleep around 3 or 4 and then either sleeping in till afternoon or taking naps in when we had morning class. One semester, I had a Mon/Wed class that was required for my major and met at 8:00 am. I also had a couple other Monday classes, all of which had homework due on Mondays. Always hated doing work on the weekend, so I would put it off and not start until Sunday afternoon after church and football. Second or third week into the semester, roomie and I both start too late on Sunday, and didn't finish our work till like 6:30. At that point, it was easier just to stay awake, so we got some coffee and played some video games until class. (believe it was Quake 3 we were into then). Anyway, we both had a pretty enjoyable night, and started doing it regularly. Work would get put off later and later on Sundays, since we knew we'd stay up all night anyway. By the end of the semester, I don't even think we were starting our work till after midnight.
