Last week, my girlfriend lost her cell phone. A wonderful passer-by found it and called me, and we got the phone back to girlfriend. Afterwards, I thought that it would be funny to make a cell phone charm to attach it to her wrist so that she wouldn't lose it again.
This is the charm on its own.
Here's what it looks like attached to her phone.
I bought a pair of handcuffs in a costume shop. They have a switch to open them if you lose the key. I opened one of the chain links holding the cuff together and attached the cell phone dangle straight onto the swivel on the end of one of the cuffs.
When I gave it to her, I put it on the phone with her back turned and slipped the cuff straight onto her wrist. She found it funny and got the joke straight away.
