The Karate Kid is a 1984 American martial arts romantic drama film directed by John G. Avildsen and written by Robert Mark Kamen, starring Ralph Macchio, Noriyuki "Pat" Morita and Elisabeth Shue. The original film has been followed by several sequels, an animated television series and remakes.
After Stewie is released from his bubble in "The Father, the Son, and the Holy Fonz", he says to Brian that he and his friends at Cobra Kai will take him down, referring to the name of the gang of bullies in The Karate Kid.
In "The Most Interesting Man in the World", the guys catch a more realistic version in which Ralph Macchio mouths off at Johnny for trying to cripple him.
The Karate Kid is parodied in "Once Bitten" as 80s Teen Movie at a Realistic High School where the real kids think performing karate makes the guys losers.
