What's the most unexpected thing you've had in your backpack at school/college?

I had a stink bomb, I had been a bit of a knucklehead and was kicked out from one high school to another.

When I got to my new high school they forced me too join JROTC because "PE was suddenly full". They just thought I was trouble...

Anyways, I took a really foul stink bomb that comes in this like glass container that you have to throw on the ground to crack open and stink up an area.

(This was Bush era and I was very anti bush and influenced by 2pac, I didn't wanna prance around roleplaying in a white man's army youth camp)

Well I was really mad they were making me wear those dorky outfits and I didn't wanna wear it that day, so I popped multiple packs of stink bombs into the JROTC classroom. I had some spot on baseball ⚾ aim because I threw 3 of em, from a good distance and they hit the $ spot right on the JROTC instructors podium under the BUSH portrait he made us to the pledge of allegiance towards, the US flag was next to the portrait. I threw it right before the class bell, and went to the bathroom. When I came back, lol everyone had evacuated the classroom it was unbearablem I played stupid asking what happened. Lol my fuckin squad leader whatever TF his rank was, told me that someone threw some stink bombs into class and that it would take place outside.

I'm very proud of that moment looking back. Oh and it was unexpected because I bought them and put them into my backpack from a swap meet trip earlier that week and I forgot to remove them at home.

One of the dorks from my JROTC class is the neighborhood LAPD pig where I live now not far from that High school, he remembered me and how I was trouble when he came to tell me to keep it down last year, when I threw a party.
