The floor of the dorm I lived in during college had this communal vacuum cleaner and while the rooms got cleaned properly during every now and then if you wanted your place vacuumed you had to use it (unless you were rich and had your own or something crazy like that). Obviously like anything communal it was old, got treated like shit and as such probably dropped more dust then it sucked up.
Regardless, one day I was using it and as usual it cocked up. Things often got caught and blocked it up and stuff like that so with a sigh I started to pull it apart. Eventually I find a nice big dustball blocking the tubes and yank it out. What had caused this behemoth dustbunny, you ask? Nothing other than a fancy ring with a big fat diamond or something on it. I assumed it was fake or whatever but I put up a notice on the floor's noticeboard asking if anyone was missing a ring and when nobody had responded a few weeks later I took the sucker down to a jeweler, and whaddayaknow: it turned out to be genuine. I sold that baby for $400 and that was probably with the jeweler ripping me off completely. The first thing I did was pay for that communal vacuum cleaner to get repaired. It was the least I could do.
... OK so I didn't actually get the vacuum cleaner repaired but it made for a good end to the story now didn't it?
