A. A phrase made famous by Star Wars episode, The Empire Strikes Back. It is the pivotal plot twist in the movie and is usually misquoted in a feigned Darth Vader voice as “Luke, I am your father,” whenever someone named Luke introduces himself to a Star Wars fan. Star Wars purists maintain the full quote is actually “No, I am your father.”
B. A phrase that someone named Luke growing up in the 1980’s would hear at least twice a month by random people who always make a ridiculous attempt to simulate James Earl Jones’ voice. They usually follow up by saying “I bet you never heard that before!”
