The Professor Bot is an evolved robot analog to Professor Farnsworth (though he goes unnamed in the series). He appears in "A Clockwork Origin" when Farnsworth explains that the robots on his new home planet evolved from some "...filth-gobbling nanobots..." that he released just days earlier. Professor Bot accuses him, saying "HE SPEAKS LIES! The earth evolved in eons, not days!" as a parody of the tirade that Farnsworth released on the creationists gathered at Wozniak Academy just days earlier.
