What part of the word "comparing" don't you undersatand?

Easier than shrinking a stick, or picking up my twin brother's

Magic numbers??????? ..that would be what; 4,5 ?????

The only magical numbers that concern me, at present, are those "less
than zeros" which relate to a natural physical entity. As NO DHR has
yet to produce one, I can now forget them, as surely one would have
appeared by now (especially as I offered such a good reward)

You think implying that I suggested any such thing gives you kudos?
Basically, it is just a form of slander and deceit.

Sorry; I thought that you understood Doppler.....my mistake!
