"Brother's Little Helper" is the second episode of the eleventh season of the American animated television series The Simpsons. It first aired on the Fox network in the United States on October 3, 1999. In the episode, Bart floods the school gymnasium and the schoolyard, which prompts the school's principal Seymour Skinner to diagnose Bart with ADHD. Bart is prescribed a psychostimulant drug called Focusyn (a parody of (Ritalin) and which sounds similar to the related drug Focalin, a drug released six years after the episode aired), and initially starts paying more attention to his studies. After a while however, Bart starts turning psychotic and is convinced that Major League Baseball is watching over the people of Springfield.
The episode was directed by director Mark Kirkland and was the first episode staff writer George Meyer received a sole writing credit for since the season 5 episode "Bart's Inner Child". Meyer, who was facing some psychological difficulties while writing the episode, felt so dissatisfied with the episode's first draft that he turned it in with a pseudonym. The episode satirizes the perceived misdiagnosis of behavioral disorders in children, which was a controversial topic at the time the episode was written.
The episode features former Major League Baseball player Mark McGwire as himself. Following its broadcast, the episode was positively received by critics.
