Some people contacted me recently and said I was misguided for givin Finchaser that name. Some comments:
"Well he might be an OLD BASSTURD, but he's not grouchy!"

Small problem with that.
If I called him "OB" it would sound like a tampon commercial.

OR...
Obi Wan Kenobi, "OWK"

But OWK is nowhere as cool soundin as OGB.

So as far as I'm concerned, the OGB is a perfect fit, even though he's only grouchy at most once or twice a week.
