Well, since these threads seem to be all the rage with the young'uns I thought I could give it a try.
My candidates are:
GP: Dr. Jonas Venture sr.
Tollwutig: The Phantom Limb
Theory?: David Bowie
Thefremen: Dr. Byron Orpheus
King Nintendoid: The Monarch (or King Gorrilla)
So that's what I've got, anyone else?
