A Cold Day at X was the ninth episode of Fillmore! to be produced and the ninth to air. It was originally broadcast on November 23, 2002.
Mrs. Cornwall's pre-algebra final is legendary for its difficulty, and the word is that some students aren't willing to play fair. Fillmore camps out in the classroom to protect the answers, but a sudden blizzard closes the school, leaving Fillmore trapped and alone. When the would-be thieves come for the exam, Fillmore is drawn into a game of cat and mouse where honor is the only prize worth winning.
