That's because you're about to prove to everyone not already aware of
the fact that you're a complete moron. Watch:

I couldn't possibly add anything to prove the point better.
Please keep your imaginary mathematical pollution confined to your
"consciousness" groups, although alt.usenet.kooks could use your
