Adam becomes jealous when Derby accidentally invents a miracle hair growth formula. When someone wants to market his formula, Derby has to recreate it but cannot remember what the formula was.

Memorable Quotes


  • Even though Ivy preformed CPR on Preston Pickles, she did not pass because Mr. Tater said it only works on the dummy.
  • Innuendo: Derby tells to Adam that he proved the hair mixture in "other parts".
  • Derby's wildest dreams are ordering lots and lots of pizza, as revealed in this episode.

Running Gags

  • People proving the hair mixture.


  • Principal Tater is a principal, not a teacher so he shoudn't be in the CPR class.


  • Pac-Man (1980s)- When Ivy decapitates a dummy, the sound of Pac-Man when he dies is heard.
  • Apocalypse Now - Principal Tater uses the final lines from the movie. "The horror, the horror."
