Stephen Hawking (character)

Stephen Hawking (born 8 January 1942) is a British theoretical physicist. He is a brilliant scientist who is considered is the world's smartest man (although he does not believe in this in real life) who cannot talk or walk and has to use a wheelchair to move around and uses a voice synthesizer to talk. He first appeared in They Saved Lisa's Brain, and later appeared in Don't Fear the Roofer. His most current appearance was in Stop or My Dog Will Shoot where he once again used his propeller to get out of a dangerous situation. He also made a non-speaking cameo in Treehouse of Horror X.

Trivia

 * Even though in reality, Professor Hawking is almost completely paralyzed, the animated version of him can somehow make appropriate facial expressions, blink his eyes and move his hands. Also, Hawking cannot use his hands in reality, and is forced to use a brain-computer interface in order to operate the computer on his wheelchair and speak with the voice synthesizer.
 * Like in the show, Professor Hawking in widely believed to be the smartest man in the world. However in actuality, he denies this because he said that if he was, it would be very humiliating.
