Well, I got to say, I never thought I would be fascinated with a thread such as this but it was instructive, funny and informative. Heck, it took me quite a while ,being new to this site, to figure out just what the heck "pb" meant. My operator errors usually lead to a few pb's not just one, but I do believe one of the commentators is right when they talk about the absence of acid. Thanks for the informative thread.
