- "[Leonardo] might have hidden a clue in one of his other works. Ergo, I sent Bender out for a copy of The Last Supper"
- ―Professor Farnsworth
- "I'm back. Everyone at Kinko's was an idiot, so I just brought the original."
The Last Supper is a famous mural painted by Leonardo da Vinci in the 1490s in Milan, Italy. He included clues in the painting, to help point the way for a shadow society of intellectuals who would follow.
First, he included a mysterious hand holding a knife that points at St. James the Lesser, but does not belong to anyone pictured. In addition he painted one of his own inventions, Animatronio into the scene, before painting over the robot. And finally he left the robot's legs visible as "wonky table legs."
