2x17 - The Middle

Frankie once again goes head to head with Brick's third grade teacher, Ms. Rinsky, when Brick gets a D on his math test and Frankie thinks poor teaching skills are to blame. But Frankie wonders whether or not she can make the grade when Ms. Rinsky requires that she and Mike attend a class to test their own math skills. Meanwhile, while begrudgingly watching over their crusty, old aunts, Axl and Sue mull over a plan to accompany Aunt Edie on a search for a time capsule she buried when she was young.
