I thought this might be about my old Latin teacher. She taught us to sing well known songs in Latin. I still sing "Row Row Row Your Boat" in Latin.
She would give us extra credit for (attempting) to translate pop culture slogans and making posters for her classroom. I appreciated that because I did not do too well in her class and the extra credit helped.
I'm surprised at how much I use what I learned in that one semester though.
