"It looks like this particular instance run has gone down like a lead zeppelin, to quote an infamous phrase. (Joke's on you, Entwistle -- at least John Bonham died before he got old.)
According to Joline of <Deep Thought> on Stormreaver, a group member disconnected in the middle of an instance, and the whole gang was stuck waiting for him to make his way through the 600-person queue. They started passing around some of those paper zeppelins you can buy at the Dalaran toy shop to pass the time. There's a little trick where if you run away from a zeppelin, it continues following you, but you also get it in your inventory to throw back. Zeppelin + Bug + Time + Empty Instance = This Picture. Hmm ... these zeppelin stacks remind me of something from college. Ah, yes. The big ol' pile of footballs. Such memories."
