what are the oddest mysteries that you've found?

ok. so it was senior year, and senior field trip day (high school). going to six flags (theme park). anyway, it was my turn to go onto the bus and id was required. i looked into my wallet and my id was not there. i used my drivers license id however to get onto the bus and go on the trip. until this day, i lost my school id. and i had it in there the day before because i have short day and you need to show your id to get off campus for short days. there was a sticker on my school id for short day students. gone. scares me too.
