Fooker was GPF Software's system administrator in the beginning. He is a bit crazy and very unhygienic; his apartment has been condemned by the EPA. (See the Slime Molds below.) He was well established as a Linux zealot but has since tempered his OS elitism with the aid of his friends. The origins of his nickname are a bit uncertain, but most likely have to do with switching the metasyntactic variable "bar" with "foo" in his last name. Some characters, however, mistake his name for a similar-sounding expletive.
