I didn't understand the geek-show reference when Ebert made it, but I understand it now as the sideshow thing -- my memory had to be joegged a bit. As for not finding many references to it on Google, um, duh? The guy eating live chickens and shoving nails up his nose doesn't usually have time to work on that website.
We normal-geeks have pretty much taken the geek term for our own in perpetuity, online at least.
