"Brace yourselves, gentlemen. According to the gas chromatograph, the secret ingredient is... Love!? Who's been screwing with this thing?!"

Simpsons Top 100 Countdown
#47 Flaming Moe’s
Season 3, Episode 10 (Guide from the Simpsons Archive)

Moe’s bar is going down financially, and the beer supply has been cut off. Homer teaches Moe a new drink that he invented called the Flaming Homer, whose taste is unlocked by setting the drink on fire. Moe quickly steals the drink for his own and renames it the Flaming Moe. Practically overnight, Moe’s bar turns into an overwhelming success, including several celebrity patrons and the need for a bouncer. Homer is driven mad by Moe making a ton of money off his invention, and eventually reveals the secret ingredient which ruins the popularity of Moe’s bar, returning everything back to normal. Memorable moments include the “Eye on Springfield” opening, Lisa’s slumber party, Moe taking credit for the drink (the first time, at least), Homer landing on Aerosmith, the “Hugh Jass” prank call (my favorite of all the prank calls in the Simpsons run), the Cheers opening parody (complete with woodcuts), Moe’s belief in Tipsy McStagger, Homer’s search for a new bar (and the look on his face afterwards), the Lionel Hutz scene, Homer’s opinion of making people happy, Edna’s desperation, and the bribe Aerosmith needs to come on stage.
