Careful, I would never renounce my nuttiness, lest something awful happen to me list-wise :) Ed

Some day when you learn how to speak to people with respect, you too may get some respect of your own. Never argue with a fool, onlookers may not know the difference. Never wrestle with a pig, you will only get dirty, and the pig likes it.
