[Tabe]

Mine is a childhood nickname based on my last name. Hardly anybody other than my parents, my wife, and a couple co-workers calls me by real name. To everybody else, it's "Tabe".

As for the avatar, well, a few years back there was a web site where you could submit a photo and it would create a "Simpsons" character of you based on your photo. A co-worker friend of mine did that for our entire group, with hilarious results. Mine actually is a fairly good representation of what I actually look like and so I've adopted it as an avatar.
