| Commercial Information
Bart's Karate Lesson is the ninth Butterfinger commercial. It originally aired in 1992.
Bart is at his karate lesson. Akira Kurosawa is the teacher and starts the first lesson by throwing Bart over the wall. Akira then starts lesson number two and picks up Bart, spins him, and throws him on the ground, and his Butterfinger falls out. Akira takes Bart's Butterfinger but Bart trips Akira on the ground to get his Butterfinger back. Bart says that lesson number three is that "nobody better lay a finger on [his] Butterfinger" and starts to eat it.
