Write a parody of a song.
It’s International Country Music Day! To celebrate a genre that practically begs for parodies (tractors are lit) take a song you love, a song you hate, or a song you “only listen to ironically” (I like Evanescence and the YOI theme song too, guys, it’s okay) and write new, funny lyrics.
