Homer's Clones appeared in The Simpsons Treehouse of Horror XIII. They are created via a magic hammock which Homer purchased after stupidly ignoring the warnings of it.
At first it's all going smoothly, and the clones do all the hard work, as the real Homer gets all the credit, and they don't do say anything about it, due to being TWICE the idiot that Homer himself.
But things starts going badly, when Ned asks about borrowing the chainsaw that Homer apparently stole from Ned to begin with. But when one of the clones sees the chainsaw and misunderstands what Homer wanted done with it, the clone shows Homer the decapitated head of Ned Flanders, much to Homer's complete shock.
Terrified by Ned Flanders' death, Homer drives the idiotic clones to a corn field, shooting any that remembered the way to his house. Homer also leaves the hammock behind. But this proves to be a bad choice by him, and the clones use it to make an entire army of Homers.
In a tempt to stop the clones from overpopulating America, the government tricks them into falling off a cliff by riding helicopters attached with giant dounts. The plan was a success, but it later turns out that one of the clones remains behind to secretly live with the Simpson family while the real Homer was the first to fall off the cliff due to his obsession of donuts. Marge is terrified, but when the Homer clone gives her a back rub, she decides to live with it.
- The clones have no belly button.
- The clones appear to become progressively stupider as each clone clones itself. As a result of this, Family Guy character Peter Griffin, who is known for his own utter idiocy and cluelessness, can be seen as one of the later clones (possibly also as a reference to the rivalry between The Simpsons and Family Guy), along with the first Homer design ever and more stupid.
- The clones are a reference to the Doug Kinney clones from the 1996 film, Multiplicity.
