I've only actually pulled an all nighter once..
I ended up taking random naps during the day and ended up almost getting sick while watching Jackass 2. Which would normally be something that didn't happen. I was also pretty delusional.

Most nights, even during school, I stay up until all hours of the night and sleep through most of the day/fall asleep during first period class. xD
All summer, my normal wake up time has been between 12 and 3pm.
