Has Tom Wilson tried "TellAFuckingJoke.com?" Seriously, there is no joke in that panel. I mean, Ziggy was always full of bad jokes, but at least they were attempts. This is just...I don't even know what to categorize that as. Man. Pure awful.
I'd say as long as it wasn't a porn site, I'd feel ok making a reference to it. Cybersquatters seem to have every possible domain name taken, so it's hard to pull a 555-1234 when it comes it a domain name.
FYI...Gannett (the Borg what own USA Today) have owned the Green Bay Press-Gazette, the town's oldest paper, for years now. They bought out the "little paper that could" competition, the Green Bay News-Chronicle a year or two ago.
