I'd save the staple and show it to the doc. He should recognize it if it is his. Its nice he is so available! Many people in big cities wait to see their docs. Yours is trapped on an island with you!!
No more late night crunchy staple snacks for you!! I wonder what else will come out of it? Maybe something you've lost recently? Socks? Keys?? You never know. Money would be nice. Sorry. Just getting silly.
