What is a black squirrel wake-up call? What do the letters in UEFI stand for? We asked LinuxCon and CloudOpen attendees to give us their best answers to these and many more Linux trivia questions on video. They played along and came up with some great answers -- some more correct than others. The video was then shown on the big screen in front of hundreds of Linux professionals who laughed appreciatively, and knowingly. Thanks to all of our participants for helping to make this a fun conference!
