in your formulas. Work's great. And ya know what.......
it works! :-)

P.S. See they even have "weasel symbols" in mathematics.
But then you knew that didn't you?
I wonder why it didn't occur to you to use this though.
Hmmmmm are you ignorant of mathematics or did you intentionally
avoid this because it makes your point look..........ummmm......silly?
