Interesting topic...
As far as odd goes, my film canister of
Disneyland Splash Mountain water from 1989 has to take the cake there. Yes, water from Splash Mountain, you see, my family had just moved to Texas, from the L.A. area. I had the oportunity to go back and visit some of my friends that I had just left (this was when I was in high school) and we all did a day at Disneyland. While in the backup of logs returning to the station right before the last scene where Br'er Rabbit has gone back home. "Born and bred in a briar patch and I'm here to STAY!". ANYWAY, some irresponsible guest had thrown their empty 35mm film canister in the show scene, and it was within my reach, so I picked it up. Then I filled it with water and we joked about collectors Splash Mountain water....yadda, yadda, and my friend Sergio.....who I have lost contact, so if anyone knows him, please let me know.....well, he said jokingly, that I should keep it. So I did, and still have it to this very day.
