Wynand Mullins recently boarded a Sydney, Australia flight wearing a T-shirt with The Princess Bride' movie quote "My name is Inigo Montoya. You killed my father, prepare to die."
Mullins was asked to change his shirt (pictured below) after other passengers on the Quantas airline felt threatened, reports the Daily Mail.
Mullins told Stuff.co.nz how surprised he was that people didn't recognize the line from the movie: "The flight attendant said to me: 'Are you able to remove it because some of the passengers are quite intimidated by it.' I thought it was all a bit silly. The person next to me was laughing, because they knew the movie."
Mullins told the flight attendant that he didn't have a change of clothes and joked that he hoped he could wear the pilot's shirt.
Mullins added: "I wouldn't be surprised if they had someone watching me the whole time."
For the millions of people who do not know the line, actor Mandy Patinkin who plays Montoya, a swordsman on a mission to revenge the death of his father, utters it (video below).
