On tonight’s episode of Futurama Fry, Leela, and Bender descend into the sewers to go find Nibbler. They end up in the city of the mutants, and in their church they worship a nuklear missle. Is this a reference to some classic science fiction?
“It will be many a year before someone flushes another guitar…”
Benieth the Planet of the Apes. The underground humans worship a doomsday bomb. Identified by the alpha and omega on the fins.
It’s a reference to Beneath the Planet of the Apes (1970), the first sequel to the original Planet of the Apes (1968). See http://en.wikipedia.org/wiki/Beneath_the_Planet_of_the_Apes.
The bit also included a hysterical line:
Fry: You guys worship an unexploded nuclear bomb?
Mutant: Yeah, but nobody’s that observant. It’s mostly a Christmas and Easter thing.
…which unfortunately contradicts a later Futurama concept: “Christmas” in the 31st century has long been renamed “X-Mas” and turned from a festive occasion to one of terror.
Except among the sewer mutants, who maintain the older traditions. And some of them might actually be flying reindeer with glowing red noses! 
w00t! I win by one minute!
But you have a cite, and spell it right.
But still!

Oddly, Saddam Hussein had a mosque built with the minarets looking like missiles. [/slight tangent]
