Don't know about the formal definition, but some advertising lines certainly are instant classics ;-). I'm still recovering from the "Official digital camera of the Internet" slogan in that other thread (and, in fact, wonder whether Al Gore approved of that statement - given he's the Inventor Of The Internet, right? ;-)).
Classic is probably going the way of "vintage" ("wine year", now pretty much meaning "used crap") and "collector's item" (surely, if people collect beer bottle caps or desiccated flies, there must my someone out there who will regard my particular piece of junk as an item worthy of collecting?).
Yes...
The term "Disney Classic" somehow instantly entered my mind when I saw this thread...
