Professor Frink's lab is destroyed and Bart and Frink are arguing whose fault it is. It started during a school trip to the lab where Frink shows his Contactinator, a set-like broadcasting device used in the attempt to contact and communicate with extraterrestrial life forms in the vast reaches of the cosmos. Frink decides to give the class a demonstration. He says into the computer's microphone: "Professor John Frink of Planet Earth Calling all sentient glavin life for friendship and possibly more." When he does not get any answer, the whole class laughs at him.
