Despite the rumor that it's an acronym for "Big Wanking Liar", it's my initials (BWL) - short for Bruce Wayne (yes I was named after Batman and damned proud of it!) LaWall.    I decided to spell it out so as to underscore my love, respect and admiration for George W. Bush, commonly referred to as "Dubya" around here. (Please see this thread).

My previous Mudcat incarnations were "Bored at Work" (which is exactly what I was when I chose it, only to decide later that it was a really stupid name) and "Bedubya" (which I couldn't resuscitate due to having forgotten my password).

FWIW I almost always sign off with my real name.

Bruce
