Let's see.....
Dan the LAN man - current. I'm Dan and I'm the LAN Administrator.
Barracuda/Fishy - My last name rhymes with Barracuda. It was shortened to Fishy later in grade school.
Dano - H.S. nickname (book 'em, Dano)
Dumbass - self-inflicted, needs no explanation.
Oh, one more, my wife calls me God. "God, I love what you do to me. God, it feels so good. God, do that again."
