On the episode where the whole town of Springfield is brainwashed by the phony religion called the Monotrems, (I think that's what they're called, i can't really remember. the religion with "The Leader" as their god). anyway, at the start of the show where everyone is watching the movie about the religion, (basically, being brainwashed, except for homer, who is more interested in a bird outside. at one point, at one point, you can clearly see that Homer is in the background if you look, about in the middle really. But Homer is really at the very back, with the priest-like people.

-My point is, does homer have an unknown twin, or he magically teleported to the back every time it showed it.
