How to Sink a Sub is the first segment of the 59th episode of The Adventures of Jimmy Neutron: Boy Genius.


When Jimmy sends the teachers into Hyperspace for a week and the whole school gets the place to themselves, things get a lot worse. Jimmy, Carl and Sheen's parents are substitutes, and they embarrass them. Jimmy tries to build a raging hormone bottle to send the parents away, but the parents drink it instead and rampage through the school. 


  • Jimmy's baby picture looks like his prototype, Johnny Quasar: Boy Genius. This was also seen in a series of Nickelodeon trading cards. 
  • This is the last episode where Joe Lala voices Mr. Estevez 8 years before his death in 2014. For the rest of the franchise, Carlos Alazraqui reprises his role from the movie.
