Failure To Teach

What kind of teacher writes a massive crimson F on top of his students exams when they fail? Daisys teacher! Daisy has eventually had enough of her ridiculous teacher so she shrunk him down, taped him to her exam, and snuck him home. She gives him a short lecture and then eats him and nearly chokes on him. Once the school replaces him she hopes she can re-take the exam since it wasnt recorded in the grade book yet!
