During OSCon, I went to dinner with a bunch of MySQL folks - Henrik, Mats, Lars, and Rich (audio engineer for the OurSQL podcast). On the recommendation of some friends in Portland, we went to Le Bistro Montage. There, we raised our shot glasses (full of an oyster shooter) and sang Helan Går (well, I did not sing because I have not familiarized myself with the song -- I am not a big drinker!)
You can watch it directly on YouTube at http://www.youtube.com/watch?v=ZG1r2QAVD8U. It's only 40 seconds long.
Folks will be pleased to know that nobody threw up :)
