Well, unidentifiable objects could be the perfect gift - for lovers of puzzles, crafters / handymen / women, or anyone with an imagination. 
- Could fill it with rice and give it to a musician (maracca
s) - Fill it with cement, seal, get a matching bowl then give it to a chef (mortar and pestle)
- Or, forget the bowl and give it to anyone with a desk, because it's now a paperweight. For a personal touch, bedazzle it!
- Get a display rack and you've got an instant ornamental, abstract sculpture that everyone can pretend they understand the message behind.
- Leave as is and give it to a tiny bodybuilder.
- Put up hooks on either side of a door, rest the doohickey on it - instant lock.
- Drill a hole in one end, add a glowstick and you're now the owner of a lightsaber (or, for the budding ninjas, add a blade and turn it into a sword).
- Find small momentos, place inside - voila, mini time capsule.
The list is probably endless. ^_^
Some good ideas, digi. How do I fit all of those words in the title?

"Get a display rack and you've got an instant ornamental, abstract sculpture that everyone can pretend they understand the message behind." Put a title and artist sign beneath it, printed with Disjuncture in thew - Silence. Artist's name intentionally left blank.
Fill with laughing gas, and threaten to unscrew the device at a banker's convention.
Fill with small everyday objects in common use today, then bury in suitable location as a Time Capsule. (Additional benefit: in the meantime someone might have worked out what it actually is!)
Speaking of burying... buy some pet beetles and call them Bruce, Zeus, and Dr Seuss.. Once they have died, place them carefully (on cotton wool "cushions") inside the object. Bury it. Optional headstone: "Here lie Beetle Bruce, Beetle Zeus, and Beetle Dr Seuss, who perished in circumstances as mysterious as the object in which they are entombed."
Then call out beetle juice beetle juice beetle juice and they'll all reappear

Well in for a penny, in for a pound (Hopefully dont get banned)
Seeing pocket rocket has been mentioned, maybe it is for recycling certain rubber items that can be associated with pocket rockets.
Turn them inside out over the device, 1 at either end, and throw it in the dishwasher.
The most apt "user name checks out" I've ever seen on eBay.
