“What to Expect When Bart’s Expecting” – Season 25, Episode 19

This article isn’t put into any specific order of “Worst to Worser” but if I had to name my least favorite episode of the Simpsons, it might be this travesty. Here, Bart uses a voodoo doll to try and give an annoying teacher a stomachache.
Instead, she ends up pregnant and other people ask Bart to help them conceive children, too. Eventually the mob and Fat Tony ask Bart to help them knock up a racehorse. It’s all very dumb, not very funny, and is far too outlandish even for season 25 of the show.
