I work in the CS department of a university in a large, coffee-and-samba oriented country that shall remain unnamed.
Some of the grad students used to have a large metal cabinet as a divisor in their shared office. Besides being festooned with stickers and year-old notes nobody had they keys for it -- they just assumed it was a convenient piece of metal used to hid their screens from others' views.
When we changed offices we had to move it, and nobody claimed ownership. Being curious and irresponsible, I decided to apply the adequate amount of force to open the doors. Inside there were a bunch of SCSI cables and terminators, 8mm tape drives for a backup driver, a huge box of SIMMs (total amount of memory: < 2gb), random pieces of SUN gear, lots of ZIP disks and drives and a box of 8-inch floppy disks.
Shame on me, I kept it all. The 8-inch floppy disks are a funny conversation starter (hey, babe, want to see my 8-incher) and also a embarrassing conversation stopper (either "huh...." or "how old are you again?")
