Whenever I need a really good idea, I just get a fresh sheet of virgin paper from my desk and take out this old fountain pen I have hidden deep in the back of my drawer. It’s a 1932 Mont Blanc Ecrivain - with a cap and barrel made of glossy black pearl, and a nib made of rhodium.
I have one of those, but it is made of the crushed teeth of baby kittens, and I usually shove it up my nose to get the blood. I write on the dessicated livers of old mummies, and then scan them to save it to disc. By the time I've done with all this preparation, I usually forget the idea that got me interested in writing, so I go off and play jenga with a pair of spider monkeys until I get a new idea.
