Engrave your private key on a real key, put it on your keychain and tell everyone you can use this key to access your coins.

Alternately, engrave your private key on your privates, and tell everyone your pee pee is the key you use to access your coins.

Write down your private key on a piece of paper, put the paper into a little capsule, surgically embed the capsule into your left butt cheek.

Fill a basket with used tampons and put key in middle

That would be safe no one would dare touch those digusting things now bitpop can I borrow some from you?

Build a safe and keep your bitcoins on paperwallet there. It is exciting and cool at the same time. Even better put it in a box and bury it somewhere and make a treasure map. That is more then interesting.
