Anyone find it odd that the Disney Adventures calendar was promoting Cartoon Network, and a Looney Tunes movie as well? Not to mention all the talk about Hey Arnold and Scooby Doo.
Finally, notice that somebody named Maggie Groening is a co-writer for the novelization for Hey Arnold: The Movie. Is she related to Matt Groening, or is it just a coincidence? It would be especially weird since there were "Hey Arnold" comics in Simpsons Illustrated Magazine before Nick picked up the show.
