This is Tim, after all. Who misread a log graph. Rather than admit it, he decided it was a linear graph. Confronted with the impossibility, rather than admit he was wrong again he invented a whole new kind of graph and made up a new name for it.
All of that I could perhaps forgive (but not forget...oh, no, it is much too funny). His next move, however, was to start using it like a log graph...but instead of manning up and admitting his earlier error, he put on an arrogant air and pretended he was lecturing everyone else on how graphs work.
That's the point at which it becomes unforgivable.
