It's pretty common these days for good teachers to get creative with getting their kids excited for class and assignments, often encouraging students to get creative themselves and come up with pop-culture-inspired ways to express their understanding of material. When Mrs. Merlette filmed a video for Instagram of her and her third graders singing a math-inspired remix to "Old Town Road" by Lil Nas X featuring Billy Rae Cyrus (and a hyped Melissa & Doug plush giraffe?), she likely thought just sharing her energetic kids was the peak of her day . . . until Lil Nas X himself saw it online and tweeted directly at her. Check out what he had to say, and try not to rewatch the video of her students a dozen times.
