Hmmm...I had to look - my car key, my house key, my gas gadget/credit card type thing, my membership card to planet tan (spray tan only), a weird looking key that must be important or it wouldn't be there and 2 overseas motors key fobs. I don't have anything interesting. I need to go keychain shopping.
BTW, I used to carry a pepper spray on my key chain and learned that they need to be tested occasionally to be sure they still work. I think I had it for years and felt so safe, til I heard that. Don't know if they still work that way or not.
