Miller's Last Theorem:

For any drawn graph, if the graph is intended to cross the (x,y) axis at the point (0,0), yet due to the artists inability to draw straight, the line crosses the y axis at a slightly higher point, then the following occur:
1) The point where the line crosses the y-axis should be labelled as (0,75)
2) The y axis carries on until the point 1,500,384.8

This however will only occur on a graph, that has not yet been drawn with a scale.

An example of Miller's Last Theorem is shown below:
