Professor Liu was known to be one of the toughest at the university, but a few words of wisdom to survive her class had been passed down through the years. For one, while she wrote a lot on the board, students knew to pay the most attention to her lectures when she walked around the classroom. She wanted to ensure students were actually paying attention to her words.
So as she walked up and down the rows that day, the entire class was feverishly taking notes as she talked, “And so when we have a heterogeneous catalysis, we can study the Haber-Bosch process in order to...what the hell?”
The students were puzzled by her tonal change until they looked at their own notes.
“That’s not my handwriting. I don’t write hearts on my i’s,” A young woman spoke up, “And this is not my voice! Or my body for that matter!”
“And I’m not Professor Liu!” Professor Liu’s body said, “I’m Doug! I sit...over there.” Doug looked to see his body still sitting there, “Holy shit! I’m looking at myself! And I’m in the teacher’s body!”
The entire class was in chaos with everyone swapped around.
