One day as I was walking through the student lounge, a kid I know called me over to sit with him. Typically, the entire place is full of the same 20 or so people, who are either playing Magic the Gathering or something similar, and not being a fan of this, I do not hang out there (That's another story I guess, it seems like the typical taboo "dork" area of campus)...But anyway, the kid was sitting there, called me over, and asked me to take a look at some of his sketches. He wanted me to make the pieces he had designed, and make them into a wearable costume. As we sat there, and he reached into his bag, his eyes got really big, and he looked at me strangely. Come to find out he had quite a large bag of the ol' grass stashed in the bottom of his backpack, and he had forgot to take it out before going to school that day.
And on the topic of bringing things to school you shouldn't, another strange thing that happened recently was the last day of finals, when a guy in his late 30's brought the professor a bottle of Jack for Christmas. He told him merry Christmas, and I heard the professor make some weird noises. He then walked to the front, looked at me and stated that it was campus policy to not bring anything, and he was going to pretend he didn't see anything. LOL.
Additionally, a kid I know started wearing Victorian clothes this semester, including top hats, spectacles, and canes. One day the above mentioned artist/toker stopped both us, and started talking about cane the dude had. He eventually unscrewed the handle, only to reveal a 3 foot blade. The dude was bringing sword canes to school the entire time. XD
