I found a pair of earphones on the sidewalk and took them
A couple months ago I was walking home from the subway and found a pair of iPhone earphones on the sidewalk. They were really muddy and nasty but I picked them up anyway and washed them in the sink and I still use them when I can't find my other pair. They work fine, so I don't see why my sister was so shocked when I told her about this. I cleaned them out afterall.
