 The idea of having Spock give the Vulcan nerve pinch to the punk  rocker was inspired by Leonard Nimoy (qv) who was walking down the  street in New York when a punk came out of a store with his boombox  blaring, disturbing everyone around him. Annoyed, Nimoy thought "If  I was REALLY Spock, Id pinch his head off!" (According to Nimoy in  the DVD Commentary).
