Futurama Easter Egg - Secret Message in the Sandwich

In the Season 4 DVD set, fourth disk, the main menu with episode list has intermittent dialog. One is of Zoidberg saying something like, "If I only had an egg salad sandwich." If you click on the sandwich within the fridge, a lengthy alien message will appear which, when translated from the alien cipher #1 of the series, says:
----------
"This DVD includes a specially encoded Easter Egg which you are now meticulously translating from an alien language because you have no life and are a compulsive nerdlinger, how sad. It's especially sad if you don't speak English and you have to translate the alien language into English and then your own tongue and come upon a word like nerdlinger which really isn't a word at all, but still aptly describes someone who would actually translate such a word. Twice. And those of you who are reading this translation on a Futurama newsgroup aren't any better. We lurk on those newsgroups and we know what nerdlingers you guys are, too. Of course, you're also probably our biggest fans. Which is sad in its own way. But, since you went to all that trouble to translate an Easter Egg, we do owe you something. So here's a secret about the show: the writers, producers, directors, and most of the actors who worked on the show are all nerdlingers, too."
