After yet another prank from Bart, involving flooding the gym, principal Skinner talks to Homer and Marge and advices them to make Bart take a new behavior drug, called Focusyn. At first Bart doesn't want to take the drug, but pretty soon he doesn't mind and it actually seems to work: Bart stops playing pranks, actually pays attention in class and reads in his spare time. Good times don't last and Bart starts behaving very strange and paranoid. Written by Marco van Hoof <>

Bart is shown reading a book called 'The 7 Habits of Highly Effective Pre-Teens' and gives a copy of 'Chicken Soup for the Loser' to Homer. These are plays on the real books 'The 7 Habits of Highly Effective People' and 'Chicken Soup for the Soul' (both of which produced multiple sequels and spin-offs). See more »

The simpsons episode I laugh the most at
17 September 2017 | by See all my reviews

Is this The Simpsons most creative episode? No. Is it the shows most well written episode? Certainly not. The plots not really complex. It's an episode pretty much where Bart takes medication drugs, gets super smart, then becomes out of control. Sounds rather simple, doesn't it?

However where this episode does display off its radiant charm is through it being absolutely hilarious. In fact, it may be my opinion alone, but to me it's one of the show funniest.

It has so many memorable humorous lines such as:

-"Bart: Thanks for coming out here mom.

Marge: No, thank you for stopping the tank!

Bart: It ran out of gas!"

-"Homer: My god is she brave. Standing up to that freaked out.


Lisa: Dad, that junkie is your son!

Homer: Why don't you just tell everybody!"

Along with so many others. So even though I know there are many better made Simpsons episodes, I still just genuinely love this one.
