This reminds me of once when I was playing the original EverQuest. Someone named Dunn entered the zone and everyone there started OOC broadcasting anything from "Dunn!" to "Dun dun duuuuuuuun!" I was young and sheltered and didn't get the reference; I messaged the guy something like "what was that all about?" and apparently he didn't, either. Probably pretty fun to be that popular for thirty seconds for no known reason, though.
