This is my best story of a collegiate all nighter that doesn't include lots of illegal activity.
I took a physics class (BAD IDEA FOR SOMEBODY WHO SUCKS AT MATH) with two of my best friends who happened to be a Bulgarian named Georgi and a guy from Bangladesh who lived in his closet named Tapash. It was a Friday, we had this big project due that day at, according to the professor, 5 PM. However, we had inside information from a friend who was a physics major, that said this professor always left campus well before 5 pm on Fridays and that you could, in fact, drop off any projects or papers by sliding them under his office door at any point before 9-10 AM on Saturday.
Ok, great, the plan was we'd all work on these projects together to pool our resources, drink some Slivovitz in the process and then go out on the town once all was said and done. Great.
So around 3pm we get started working on this stuff. Take numerous "study breaks" to smoke cigars I'd bought for the occasion, play some Gran Turismo on the "x-station" that Georgi had built - it was a combination PS2 and Xbox lol. It quickly turns into about 7-8 PM before we actually got any real work done and finally we finish at about 11 pm.
So, the 3 of us march down to the science building to drop off our papers at the professors office. PROBLEM. The building is locked up tight. We call some friends who are nerds thinking maybe they're still in there. No go, can't get in the building. So, we decide if any campus security see us we're just going to claim that one of us lost his wallet earlier in the day while we start trying windows and other doors to see if they're unlocked. Eventually we find a window that will open from the outside, but it's one of those old style slat windows so the opening is VERY slim. Tapash thankfully was very skinny so we picked him up by his waist and inserted him into the window. He yelled out that he could open the door.
So, we throw the papers in after him and start walking to the door we'd assume he'd exit through. He opens the door about 2 minutes later and says that we're good because there were papers all over the floor in his office that he could see laying in there. JUST, then a flash light gets shone on us, and who is it but campus security. They ask us what the hell we're doing in the science building at 11 pm on a Friday night, we inform him, as per the plan, that there was a lost wallet. Campus security guy nicely opens the door for us, escorts us to the room we say we need to visit, no wallet is found of course, and we head out to find more mischief. I ended up not coming home until something like 10-11 AM.
