# List of Pinky and the Brain episodes

The following is a list of episodes for the Warner Bros. Animation and Amblin Entertainment animated television series Pinky and the Brain, which ran from 1995 to 1998. The series was a spin-off from another Warner Bros. Animation's animated series, Animaniacs, and includes some of the Pinky and the Brain skits that were created as part of that show.
Pinky and the Brain was later retooled as the short-lived Pinky, Elmyra & the Brain, which ran in the 1998–1999 season for 13 episodes. The characters eventually returned to their roots as an Animaniacs skit in the 2020 revival of that series.
Outside of both the original Animaniacs and its revival, there were 65 Pinky and the Brain episodes produced.
The lists below are ordered by season, and then by episode number. Several episodes included two or more skits; these are identified by the segment number. The episode list reflects the show as aired in repeats and syndication and presented on the series DVDs; some initial Season 1 episodes had two or more programming variations on their first run.

Brain becomes frustrated and creates a new holiday (Wink Martindale Day) that closes the post office, thus preventing Snowball from mailing the chain letters. Snowball then tries to convince Pinky that Brain is only using him (and offers him fudge), but Pinky refuses to believe him. Later, Snowball buys out the world with his incredible wealth that he has had Bill Grates, the world's richest nerd (a parody of Bill Gates and leader of Microsponge (a parody of Microsoft)) sign over to him, and builds a Pinky-themed amusement park. Pinky begins to consider Snowball's offer, to which Brain replies, not knowing about Snowball's talk with Pinky, "Oh, go ahead, Pinky, I don't need you. What, do you think I just have you around so I can steal your brilliant ideas and claim them as my own? That I'm just using you? Oh, yes, I'm using you for your brilliance."
