Take a message

Every time I am on the phone and need to take a message I can not find a pen that works. I find tons when cleaning up but then when I need one they disappear. I buy the packs of 20 pens at the store, we always get random promotional pens from companies, and I know I sometimes accidentally take a pen that I use to fill out forms at doctor offices and such, but they are never there when needed. I usually end up finding a broken piece of crayon or I quickly open Word on the computer to type the message up.
