I like the Chamber of Commerce CC as well, if only because the person doesn't know that the CoC is nothing more than a bunch of businesses that get together to market/network to and with each other; it's all about the interests of the businesses alone. Someone mentioned the BBB as another lol-worthy CC, but at least they have things in place to facilitate fixing complaints between businesses and clients (even if in this case, they'd do nothing); they represent a little bit of both the interests of the businesses and clients.
