The Middle S01E05 The Block Party.

Brick's teachers tell Frankie and Mike that Brick tested as "socially challenged," so Mike thinks basketball is the answer to help Brick interact with others. When that fails, Mike enters the neighborhood block-party lawnmower contest and discovers that Brick has a talent for souping up machines. Meanwhile Frankie joins the booster club to raise money for new football jerseys for Axl's team, but Axl refuses to give his old one to her.
