A Bic pen is capable of scribbling 2 to 3 kilometers worth of doodles before giving out.
Another neat detail: the little hole in the body of said Bic pen assures the same pressure both within and outside, helping avoid leaks and mistakes and similar catastrophes.

While we’re talking about pens, have you noticed that once pens give up on life, you simply have to furiously write (as much as it is possible to furiously write) on a shoe sole and it’ll wondrously start again? It’s a phenomemon that’s caused by the friction of the rubber tread, which helps to dislodge any dried ink. This liberates the oppressed pen of the obstruction, letting it joyously get back to its function.
