Still from The Simpsons S20E18: Father Knows Worst

The episode in brief

When Homer observes Bart and Lisa struggling in certain aspects of their academic and social lives at school, he becomes a proponent of "helicopter parenting," the process of closely monitoring a child and forcing them to succeed. Homer takes hovering to a new level when he chooses a nearly impossible subject for Bart's balsa wood model-building competition and gives Lisa some not-so-friendly advice on how to make friends. Meanwhile, Marge discovers a sauna in the Simpson family's basement that she finds hard to resist. Blackboard: 'I will not put hot sauce in the CPR dummy'.

FAN DESK VERDICT An all-timer. This is the episode you show someone to explain why The Simpsons matters — clear the evening and watch it properly.
