I've recently been thinking about getting a business card holder to carry around, because I now have both Plinky and Farewell Typewriter business cards I could hand out. The only trouble is that I'm out of room in my pockets. See below.

Key ring
Keys are necessary to access my car, house, office, studio, etc. There's also a Swiss Army knife in case I get into a Swiss battle.

Rental car keys
Funny story! So I was in San Francisco in a parking garage, and all of a sudden WHAM! this giant concrete support beam sneaks up on me and runs into the side of my car door, scratching it and taking off the driver's-side mirror. At least that's what I told the insurance company.

Jimi wallet
This thing is the best wallet I've ever owned. It's $15, slim and hip.

ChapStick
Dry lips don't get the ladies.

Extra peppermint gum
I've written about my love for Extra peppermint gum before, but I've chewed this same gum for at least 10 years. Hope it doesn't have anything awful in it.

Hipster PDA (& Pilot G-2 pen)
Merlin's simple little invention has been a godsend for me. I've found it invaluable to have something on hand to catch all the little ideas that pop into my brain or are put there by other people.

Guitar picks
Because you never know when there's a guitar to be played.

iPhone
Duh.
