Hawking also appears in The Beast with a Billion Backs as his own head in a flying jar, leading a scientific convention organized to study and discuss a tear in the universe. He says that despite writing a book about it, he has no idea what it is, although he has already cashed the check he got for writing it. Apparently he has the ability to shoot lasers that stun people from his eyes; he himself is surprised, remarking, "I didn't know I could do that" after stunning Professor Farnsworth and Professor Wernstrom. He also makes a brief appearance during the "Future Challenge 3000" segment in " Reincarnation ".
