"And so, due to the anticheiral integral of the epiglottal hypothalamus, it is an obvious deduction that left handed people should not exist," droned the professor.
He looked up at the class. They were all staring in rapt attention at his proof cast on the screen by the overhead projector. This is good, he thought. Proper. Um. Somehow, getting this much positive attention made him suspect something was amiss.
"The exposition is clear, yes?" he asked.
They stared.
He figured he should probe some. "Miss ... ah ... Willows, what are your thoughts on this?" He was pretty sure she styled herself left-handed. He had seen that her handwriting was sinister, yet, flowery. The juxtaposition did not bear thinking about.
"There's a hornet crawling on the overhead," she said, mesmerized.
That was not an expected response. "Uh." The professor turned, and sure enough, a hornet was being projected crawling all over his proof. Rather frantically. It tried to fly, but it landed on the projector again. It was probably following the projector light. The hornet crawled more, then stopped, rolled on its side, and started shaking its legs.
"It's getting fried to death!" said another student.
Here I am, thought the professor. A selfless pioneer mapping out the forests of knowledge. Revealing truth to the world. And this, this is what the world makes of it ... I'm being completely ignored.
"EWWWWWWWWWWW!!!" groaned the class.
This was first posted to reddit/rWritingPrompts in response to the prompt "Left handed people should not exist". The prompt was removed by moderators immediately after I replied, so nobody saw the story. The general plot (fly fried to death on overhead) actually happened when I was a kid and my aunt Gretchen brought be along to a lecture at the University of Akron. It was a very memorable experience. I have no idea what the class was actually about.
