The latest discourse on my dash this April 14th of 2017:

Using spaghetti as a drawing tablet nib

An actual genius, June 12, 2011:

Buy a roll of round ~1.65mm(~0.065 inch) weed whacker wire and you have enough nibs to last you twelve lifetimes

A better idea:

Use the money you were going to use to buy the weed whacker wire and just buy the nib replacement.
