never explicitly stated. In the episode "Mars University", when asked what he is teaching, he responds: "The same thing I teach every semester, the mathematics of quantum neutrino fields. I made up the title so no student would dare take it"; however, this declaration has not precluded the professor from demonstrating mastery of whatever field of science is convenient for a given episode's plot, as shown in Bender's Big Score when he proclaims, "I can wire anything directly into anything! I am the Professor!", proceeding to link Hermes' disembodied head to the ship's computer. Approximately 100 years before the series' timeline, he taught a young (not yet Professor) Wernstrom, whom Farnsworth regarded as a prized student. After he returned a pop quiz to Wernstrom with a grade of A-minus (for poor penmanship), the two became bitter rivals (established in "A Big Piece of Garbage"). Many episodes' major plot points are introduced by Farnsworth announcing, "Good news, everyone!" or some variation thereof, either to unveil his latest invention or describe the company's latest delivery assignment. On the very few occasions he has actual good news, he often opens with "Bad news, everyone!" After Fry resigns from his job in "Law & Oracle", he states that he only says these phrases to make Fry "feel better about his pointless job." Another is his exclamation, "Sweet zombie Jesus!" He often says "Eh Wha?" when unaware of the situation, or when someone questions a statement he has just made. The Professor often makes mutually contradictory statements just moments apart; this happens especially often when briefing his employees, with the prevailing second statement canceling a much more reassuring first sentence. The Professor rarely worries about the safety of the crew, viewing them as a means to an end, as evidenced in the first episode, where he is indifferent to what happened to his previous crew and only focuses on getting a new one. Farnsworth's employees later discover that their predecessors died while gathering honey from Space Bees ("The Sting"). The Professor issues his new crew the previous crew's career chips from a manila envelope labeled "Contents Of Space Wasp's Stomach" ("Space Pilot 3000"). It is established in the episode "Mother's Day" that the Professor was once Mom's lover and employee. However, they could not maintain their relationship due to Mom's lust for power, including when she decided to weaponize his "Q.T. McWhiskers" toy, prompting them
