Party Night[]

Party Night title


After learning that Rudy won't attend Vanity's big party, Elmyra begins sobbing uncontrollably. To stop her crying, Pinky and The Brain use the Patty Ann suit to lure revolting slob Rudy to the event.


  • "Party Night" by the Way Cool Girls



  • Just like "At the Hop", the Way Cool girls sing the ending remix at the very end of the episode. Similarly, when it gets to the word "Brain", they sing it the usual five times with the last Brain held out.

The Mask of Braino[]

The Mask of Braino gif title


The Brain becomes "Braino", a masked crime fighter. Unfortunately, nobody in the town is responding positively to him. Elmyra also attempts to pose as a crime fighter— "Underwear Head."



  • "Braino"
  • "Underwear Head"


  • This segment, along with "How I Spent My Weekend," are the two segments of Pinky, Elmyra and The Brain to feature an animated title card where a character interacts with it (in this case- "Braino")
  • This segment uses similar concepts to the Animaniacs cartoon "Cranial Crusader."
  • Braino and his theme parodies the character of Zorro, as well as the 1957 action-adventure western series starring the character.
  • Recurring Animaniacs franchise guest-star Michael McKean makes his only appearance for this series in this episode as a grocer, a robber, and a policeman.
  • Janet Waldo of The Jetsons fame guest-stars in this episode as an old lady.
  • In the ending remix, just as Pinky sings Braino's theme, the male chorus sings "They're Pinky, the Brain, and Underwear Head, Head, Head, Head, Head." followed by Elmyra shouting "Underwear Head!".
