It's not a "Parker", but...

[John Farrell, Charter Member #33]

Watch fobs have gone the way of buggy whips and 18 cents a gallon gasoline, I filled the vacuum with a new use for the watch fobs in dresser drawers, junk drawers, and lost in the loose change collections. It's called a Phon Phob.

It requires a thin strong cord be threaded through the little holes at the top or back of the cell phone. You thread the looped end of the cord through your favorite old watch fob. I've used a Susan B. Anthony dollar with a hole drilled in it (until I needed change for a parking meter), a souvenir coin from Canada and as you can see, a doggie gift. I had a .410 gauge hull PP for a while but old ladies would not come near me.

You put the cell phone in your pocket with the Phob outside. Phone rings, tug PP which pulls CP out of pocket and before you can say "Bob's your Uncle" the CP is ready for use. Please refrain from applauding. My high level of humility makes me blush.
