Back to the original topic.
This didn’t happen in my class.
The English teacher announced that he was teaching them how to write a poem with a rhythm.
After a brief lesson he told them to try their own, saying he understood it was their first time writing a poem.
Some one said “Ride the train” and the whole class wrote the song from Journeys II.
The teacher (who wasn’t Jewish and never heard the song) was fascinated when he read the first paper to be handed in. Not only did it have the perfect beat but it also rhymed and had symbolism (the journey through life).
After reading all of them he assumed that one talented kid wrote it but he couldn’t figure out how the whole class copied it word for word without him noticing anything.
