Business is slow at Moe's Tavern and he is out of beer, so Homer shows Moe his home made cocktail, known as the "Flaming Homer," made from a mixture of several liquors, Krusty's Cough Syrup, and then he lit on fire.
Moe starts making the Flaming Homers at his bar and its an instant hit, but Moe takes the credit for Homer's drink and calls it the "Flaming Moe." Soon Moe's Tavern is growing in popularity very quickly, and even Aerosmith plays there one night.
Homer asks Moe for all the money he is making over Homers idea, Moe refuses. A Local Restaurant Food Chain offers Moe one million dollars for the recipe. When Moe was about to accept the money Homer blabs and tells everyone the recipe. The company puts Moe out of business and everything returns to the normal bar Moe's Tavern.
