The guy taking a pic of the C3PO is one idea...
Why don't more people use eBay to promote their site? (At least it would be safe for non-porn sites)
example: do something stupid like that guy did but somehow incorporate your site in the listing. I know it's against eBays policy to list domains in auction descriptions but there are ways I guess you can get around that. One being you can make your user name www_yoursite_com - they don't allow
www.yoursite.com but they do allow _com - go figure.
