Mass - not multiplied by the speed of light squared.

Build a better mousetrap

and the world will beat a path to your door,

which is going to be a much bigger problem

than a couple  of mice.

This is why most people

choose not to evolve,

and basically remain

a kind of mouse

coursing like cholesterol

through mazes of meat

and vocations of darkness.

Say cheese!
