Last week I was test-fitting cable housing and ferrules in the Ergopower brifters on a bike, and twice when I pulled the housing out, ferrules went flying. Luckily I had a small bag of them left over from previous recabling adventures.

Also, my other hobby is repairing old manual wind watches, so I'm used to crawling around on my hands and knees looking for things. Sometimes, you find things you lost previously while failing to find the thing you just lost. It doesn't help that some of the things are actual springs, so they are, so to speak, spring loaded and they can go a long way. Nothing quite like hearing a tiny *click* and feeling a tiny, ghostly touch on your face, when working on a watch movement from a company that went under over 50 years ago. Hard to order replacements!
