In the mid-late afternoon, as my attention started to wander after a long day of talks and workshops and insufficient sleep and/or caffeine, a colleague sitting next to me leaned over and whispered: "If we were students in a boring class, we'd be watching YouTube videos right now instead of listening to this speaker." So I whispered back to ask him if he wanted to see some cat wrestling videos I posted on YouTube last year. He thought I was joking, so I hit the mute button on my laptop and showed him. (note: There are 1,120 cat wrestling videos on YouTube right now, but only a few of them are mine).
We viewed cat videos only briefly, though, because as professors who teach large classes, we well know that just because someone is sitting in the back of the room doesn't mean the professor/speaker up front can't see what is going on..
