Bart is diagnosed with ADD after his latest prank during a "Fire Prevention Day" assembly at school, but his new medication makes him paranoid.

!!Tropes (YMMV tropes can be found [[YMMV/TheSimpsonsS11E2BrothersLittleHelper here]]):

* AsHimself: Mark McGwire
* {{CallBack}}: Homer mentions that he was banned from a water park for ten years (which, at the time of this episode's premiere, would be incorrect), which could be a reference to when he got stuck on the H2-WHOA! ride at Mt. Splashmore on the episode "Brush With Greatness." If it's not, then it's a NoodleIncident.
* TheCuckoolanderWasRight: The Major Baseball League was indeed spying on people, [[TheUnReveal but rather than explain why]], Mark [=McGwire=] dazzles the crowd with some dingers.
* OfCourseISmoke: The straight-edged Ned tries to smoke a cigarette while performing in the fire safety play, though his coughing is actually the least of his problems as he inadvertently sets his pants ablaze.
* ShoutOut:
** When Marge reports Bart's disappearance to the police, someone makes a drawing of [[WesternAnimation/DennisTheMenaceUS Dennis the Menace]].
** [[{{Popeye}} When I can't stop my fiddlin', I just takes me Ritalin, I'm poppin' and sailin', man!]]
