I've had some intimidating professors, but none as scary as Cornell professor Mark Talbert, who recently lost his temper at a student over repeated loud yawns during lectures. Only the professor has a microphone, so you can't actually hear the yawning in a video of the incident that's now making the rounds via YouTube.

Without knowing how loud or disruptive the yawns really were, it's hard to gauge whether the professor overreacted by screaming at the class and demanding that they turn in the mystery yawner immediately. I think calling the yawner "the one loser who has to do that when 220 other people know better" and telling him to "get up and walk the hell out" might be a little harsh, though.

Was the lecture boring enough to be yawnworthy? All we have to go on are the two words Talbert yells just before the video ends: "a kilobyte!" I really hope that "a kilobyte" replaces "but anyway" as the phrase to use when you realize you're ranting and decide to return to normal discussion. I also can't wait for the inevitable auto-tuned remix of this classroom tirade.
