When Bender becomes the new pharaoh he commands his subjects to build a statue of him one billion cubits in height. A cubit was an ancient Egyptians unit of measurement, roughly 20 inches. So Bender's statue would be roughly 325,284 miles (523,493 kilometers) high. This is 13 times longer than Earth's equator.
Leela's sandals are shaped like her boots.
A cubit is generally considered to be the distance of a grown man's arm from the elbow to the tip of the hand (also equal to "six palms" or two spans). Commonly known biblical cubits were ~17.6 inches, whereas the Egyptian cubit used in building the Pyramids of Giza were closer to ~20.3 inches
Pharaoh's Own body parts in mason jars is a parody of Newman's Own products.
The funeral singer, a look-alike of Elton John, performs a parody of the songs "Daniel", "Bennie and the Jets" and "Crocodile Rock" at the funeral of the Pharaoh. This may be a reference to when he performed at the funeral of Princess Diana.
