"one of the funniest characters in the Simpsons show, the Comic Book Guy (we haven't been told his name...yet)"
"yet" is correct, as in a recent interview with Matt Groening it has been revealed that CBG's name is in fact, Louis Lane, an obvious parody of Lois Lane, Superman's Love Interest/Girlfriend/Wife.
This was found at http://nohomers.net/cbg/, a site which also reveals such facts as CBG's prize possession, which is a rare copy of Mary Worth in which Mary advises a friend to commit suicide, and an image of a room in CBG's house, which includes a photo of Sean Connery signed by Roger Moore.
