"You should be asking yourself: Why am I the one loser who has to do that and 220 other people know better?"
Via TaxProf, who says "Cornell Prof Goes Nuts After Student Yawns in Class."
Frankly, I don't think what this teacher (Mark Talbert) did is that bad. The student didn't just yawn, he yawned in an exaggerated, loud way that sounds like intentional disrespect. The teacher indicates that this has happened more than once. How dare one student disrupt a class — a large, serious class — for his personal amusement? 220 students are there, working hard, having paid big tuition, and one loser is appropriating their time and attention and knocking the professor off stride. It's not acceptable, and why doesn't the student know that? Why should a college professor have to give remedial etiquette lessons?
