Frank Grimes first appeared in The Simpsons episode Homer's Enemy, which aired in 1997 during season eight, as a hardworking new employee at the Springfield Nuclear Power Plant who could not understand how Homer kept his job and his comfortable life. Homer invites him home for dinner in an attempt to be friendly, but the visit only deepens Grimes's frustration when he sees Homer's house, family and easy success. The scene became a reference for fans because it captures the show's darker take on Homer, and clips from it now circulate in memes about envy, work and unwanted guests.
