Frankie accidentally hits Brick in the head with a beer bottle when trying to get the trash out before the garbage truck leaves. But when Brick innocently tells his school that the scratch was caused by his mother throwing a beer bottle at him, a social worker comes to evaluate the Heck family. Meanwhile, Bob helps Mr. Ehlert shoot a commercial for the car lot.

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.

Frankie learns that Axl's PSAT's are fast approaching and he hasn't been preparing for them. Sue sets her sights high and decides to try out for cheerleading, while Mike decides that Brick needs to toughen up when he gets bullied at school.
