LOL. I know from experience that getting them _in_ doesn't hurt :-)
After removing quills from one dog, two weeks later I was wearing the
same shirt (which had been through the laundry) and a quill was still
stuck in the shirt, which proceeded to transfer itself into my skin.
I discovered it, possibly hours later, only when it started to itch.
Now, I remove them from the dogs with a pair of pliers - my wife
couldn't bring herself to do that to me (I don't _think_ I was
screaming...), and had to resort to sterilizing and using a razor
blade to cut it out.
