Is it weird to save rabbit's foot for keychain?- compion?

I have a pet bunny, the best anyone could ask for. I raised him from 4wks old and he lives in my room with me. He has a cage, which I leave the door open 24/7 so he may enter & leave as he pleases. He has never bitten me or anybody, and I continually shower him with kisses & diverse fresh fruits & veggies. He's litter- trained, and snuggled beside me. He's the best companion I ever could have hoped for. He's happy & trusting. However, I often ponder how sad I will be when his time comes and he leaves me. I'm well versed in dealing with deaths, but my question is this: is it extremely weird/odd that I would like to keep a rabbit foot's keychain from my quirky friend? Or is it just morbid and weird?
