How to Get Ahead in Dead-Vertising

How to Get Ahead in Dead-Vertising title card

In a parody of period drama television drama series Mad Men, Homer and Marge arrive at a daycare center to drop off Maggie, but Maggie is upset by her parents leaving. Homer turns her attention to a mural with Krusty's face on it. However, the real Krusty defaces sections of the mural, as it's an unlicensed use of his image. Angered, Homer pushes Krusty into a swing which swings him into a merry-go-round that spins him onto a pony, then a trampoline into a wood chipper, killing Krusty. Later on, Homer is approached by businessmen who heard of his deed. Apparently, the likeness of dead celebrities can be put in commercials for free, since they refuse to sponsor certain products while alive. They manage to convince Homer to start killing celebrities such as George Clooney, Prince, and Neil Armstrong. Meanwhile, back in Heaven, the dead celebrities (including John Lennon) are outraged by these exploits. Krusty convinces the dead celebrities except for Abraham Lincoln (who for some reason likes his exploit about him and George Washington kissing each other at a wedding commercial for a marathon,

although this outrages Washington) to descend from Heaven and stage an attack upon everyone who benefited from these exploits. The dead celebrities start killing people at the party and shoot Chief Wiggum. Krusty is just about to kill Homer when Homer asks, "What is the one true religion?" to which Krusty replies, "It's a mix of Voodoo and Methodist." and blows Homer's head off with a shotgun, killing him. When they return to Heaven, they find that Homer had locked them outside for revenge, and he becomes very, very good friends with Abraham Lincoln.
