It's slightly different; Rich had a sandwich shop called "SerfWay", whereas Erfworld just had the word Erfworld in the logo style. I think Rich's is funnier, because there's an actual joke there: A sub shop for "serfs," as in medieval peasant. Plus it was only a tiny part of the larger joke (that Celia used to sneak out in order to get sandwiches). Erfworld just sort of did a, "Hey, look! A logo! Isn't that hilarious? That is TOTALLY better than an actual punchline!"
But on the News page, Rich says that it was just a random coincidence, since he doesn't know what the Erfworld people do until they send it to him.
