My keyring couldn't possibly be more boring right now if I tried.
That's it. Car key, car remote, mailbox key (we live in a condo), and house key.
I'm looking to put something else on the ring, I need something that fits in my pocket, so light and small is good. Something 'fidgety' would be especially good. Since Googling for keyrings turned out to be a pretty futile task, I turn to the TFP for inspiration. Please post your keyrings, and give a little explanation of anything interesting you have on there.
