"I'm lacking vitamin D" might be the best, most underutilized excuse for not completing an assignment correctly that a kid has ever used. Grayson, son of redditor nerge, used it to explain to his teacher why his spelling assignment looked more like the thoughts of an anxious constipated person.

Nerge says that Grayson is no slouch in the academic department. He "spends his chore money on things like visual encyclopedias of human anatomy and chooses science documentaries over cartoons." But the kid obviously has a terrifically weird sense of humor, too.
