There was a guy that had 1 paper clip and he traded it for something on craigslist and then traded that for something.......... in the end he ended up with a used Porsche Boxter.........
If you've got a CD/DVD drive that fails, you can use the paperclip (straightned) to poke thru the little hole to release whatever disk is in the drive.
our day shift desk clerk at my dorm has a little container full of paperclips. i like to take them all out then attach them to one another forming a huge paperclip chain. it annoys the crap out of her.
