"Homer's Enemy" is the twenty-third episode of The Simpsons’ eighth season, first broadcast by Fox on May 4, 1997. It was directed by Jim Reardon and written by John Swartzwelder, although the idea for the episode came from Bill Oakley. The plot of the episode centers on the Springfield Nuclear Power Plant's hire of a new character named Frank Grimes. Homer attempts to befriend Grimes; however, Grimes ends up hating Homer and declares himself Homer's enemy. Meanwhile, Bart buys a run-down factory for a dollar. "Homer's Enemy" is one of the darkest and most famous episodes of The Simpsons, and is a favorite of several members of the production staff, including Bill Oakley, Josh Weinstein, Matt Groening, as well as The Office creator Ricky Gervais. Although Grimes makes his only appearance in this episode, he was later named one of the "Top 25 Simpsons Peripheral characters" by IGN.
