Why'd I do that?

So, I had an extra earring in my car, and thought, "Hmm, what can I do with this?" I already had earrings in my first set of earring holes, and my second set of earring holes had closed up.

I looked around my car.

I spotted a thumbtack.

I now have a 3rd earring in my ear....and a really sore earlobe.
