Return of the Nanobots is the 28th episode of The Adventures of Jimmy Neutron: Boy Genius.
Jimmy upgrades his Nanobots so they perfect his non-science homework, but they go overboard with this and correct everything in plain sight. Jimmy confronts them and tells them that flaws are okay, so the Nanobots decide to delete every human on Earth. Only Hugh and Jimmy remain and they try to delete Jimmy but he first outflies them on Goddard and sees his dad hasn't been deleted and eating pie while repeatedly saying "Endless Pie". The nanobots then delete Goddard and the trash can gets full meaning they have to dump it and everyone will be gone forever. Jimmy knows he can't let that happen so thinks and remembers his dad saying "Endless pie, endless pie" which gives Jimmy a brain blast. He makes them check his poem again which tricks them into computing the value of pi. Because pi is endless they can't stop computing its value which causes their ship to overload then explode. After it explodes everyone reappears and Hugh is very happy to see his wife and son again and he's not the last man on Earth anymore.
- Goddard wasn't seen coming back along with several other characters.
- Jimmy's poem is a reference to "I Sing the Body Electric" by Walt Whitman.
- This is the second of the three episodes the Nanobots appear in.
