Humor challenged audience?

There were a couple of inspiring presentations at the latest PDC conference: the technical DSL session, and the introduction to the Oslo Modeling platform. Watch out for an amusing moment closer to the end of the second show (around 45 min), when somebody in the audience asked how this tool is compared to XML. Don replied: “Well, it is not as beautiful as XML…” taking a long pause after it. A barely audible laugh (or two) in the audience. Perhaps he failed to deliver the subtitle for humor impaired: “XML” stands for “eXtremely Messy Language”.
