Start with a large vinyl coated paper clip that won't damage the phone.
Straighten the paper clip out.
Bend the paper clip in half around a pen or pencil.
Give it some little feet.
Now sit him up. It helps to bend the "back" a little bit forward, to keep the phone balanced, but just play with it until you get it right.
Last step: spread the legs out about 45 degrees.
Voila. Perfect for working in someone else's office.
