Maternotron Knows Best is an episode from the second season.


Jimmy creates a robot to replace his mother while she’s on her spa getaway, but when it becomes too controlling (due to setting the autonomy parameter in the mothering chip too high), will his mom come to the rescue in time?


  • The title is a pun on the saying, “Mother knows best.”
  • The background music of the title card sequence resembles the theme song of "Father's Knows Best."
  • The episode is similar to the Dexter's Laboratory episode, Maternal Combat, where Dexter creates a Mom-Droid to do his mother's chores when she falls ill and Dee-Dee gets hold of the remote to the robot and wrecks havoc, and makes another one to counter Dee-Dee. The titles are similar, too, because they both start with an "M" and end with a "T" and have the word "Matern" in them.
  • Carl and Sheen didn't figure out the robot mom wasn't Judy.
  • The bathtub scene (complete with sound alike music) is a parody of the famous bathroom scene from the classic movie Psycho. Judy and Jimmy even indirectly mention the movie "To think I step out for two measly days and you replace me with some psycho robot... with a hideous 1950’s hairdo." "No psycho robot could replace you, Mom. There’s no way I could program all your love, care and amazing ways to forgive me into a chip."
  • Around the 6:07 mark a brief sound alike version of "Maniac" plays in the background when Judy Neutron works out.
  • Cindy's aunt Susie makes a brief appearance in this episode as one of the masseuses at the spa.


Judy: (about her nails getting manicured by a group of men while carrying her car) Wow, you have never let a girl lift a finger.
Hugh: (whining about Maternotron) She didn't even let me play with Mr. Bath Time Ducky!!!
MaternoTron (to Jimmy): Where do you think you're going?
Jimmy: Uhh, outside?
MaternoTron: Too dangerous! Outside is where the Civil War was held! I'm putting you both on, (ferocious evil tone of voice) LOCKDOWN!
