geez, I haven't posted in this topic for over four months!
In case you're wondering, I don't use that signature anymore, aside from the fact I plain don't use signatures much anymore.
Anyway, to help explain...
I chose demented because it was the only D word I could think of to pair up with 'dragon.'
Then again, since I've recently had an interest in dragons... dragons aren't demented anymore.
A griffin, sometimes mispelled as gryphon or gryffin, looks like a creature with the body of a lion (I think) and the head of a hawk (a bird). Check a fantasy art site if you're wondering what a griffin looks like...
But now my signature shall be... Something from Galaxy Quest! Hey, I'm out of ideas...
Commander Taggart: Never give up, never...
Everyone else: Oh shut up!
