Based on some thread years ago I can no longer find that made me laugh pretty hard. Although maybe I was juvenile at the time. Pretty simple concept, though.
Bart vs. Springfield vs. Roe vs. Wade vs. God
Hot Chip reprise their role as Bart's nutsack, who convince Bart to torch the abortion clinic in this heartwarming Christmas episode. Guest starring Panic! At the Disco and the Muppets, who sing Nine in the Afternoon together over the credits.
Keep the Black Sabbath Day Holy
God has a procedure to remove one finger from each of His hands in order to more resemble the Crazy Cat Lady. But His recovery prevents Him from doing daily tasks, so The Simpsons have no choice but to take Him in. God tolerates some Commandment-breaking in the household such as Bart stealing Flanders' Wi-Fi and Marge committing adultery with Ghost Maude, but He is put over the edge when Homer picks up a Sunday shift at the plant - causing him to not keep the Sabbath Day holy. Featuring a Black Sabbath song on the radio while Homer works in order to justify the episode title.
South Park Already Did It
Lisa and Miss Hoover introduce the women of Springfield to queefing. Meanwhile, America's Bad Boy Bart Simpson is at his silly ol' pranks again, this time chopping Milhouse's parents into chili.
