Professor Farnsworth tasks the crew with the delivery of a sandstone block to the planet Osiris IV, whose civilization is based on what they learned when they had visited Ancient Egypt (a parody of ancient astronauts). The order turns out to be a ruse to capture the crew and put them to work as slaves, constructing a funeral pyramid for the current pharaoh, Hamenthotep. Bender, amazed with the means of memorializing the pharaoh, becomes a workaholic and far exceeds the pace of the other slaves.
