Eh, it was a silly inside joke among me and my friends in high school. We thought it was funny to just spout off random gibberish words which sort of evolved into a language... well, at least a few idioms. When something was cool, or neat or awesome, we'd say, "Dude! That was UNSEEN." And the proper response was, "Yeah, unseen like a WOMBAT."
Seems kinda silly now, but I've been using the name since I joined the SC1 forums in like 98 or 99, so why change now?
My alter ego, Crazed Ferret, which I use on the Tekken forum, came from someone who mentioned in a religious debate that maybe a bunch of crazed ferrets created the universe.
On the former subject of sad WWII stories, I read this letter yesterday:

It probably wouldn't have bothered me before, but now that I have a daughter, I can't stop bawwwing over it.
