Careful what you wear on a plane.

Wynand Mullins of New Zealand told Stuff Magazine that he was asked to remove his T-shirt because other airline passengers found it intimidating.

And, yes, we suppose if one weren't familiar with "The Princess Bride," seeing a shirt that reads, "Hello! My name is Inigo Montoya. You killed my father. Prepare to die," might be a little alarming, especially on board a plane. But in Mullins's defense: Who the heck hasn't seen "The Princess Bride"?

For the two or three of you who haven't, the movie features a character named Inigo Montoya, played by Mandy Patinkin of "Homeland." After seeing his father killed by an evil, six-fingered man, Montoya vows that when he crosses paths with the fiend, he will say, well, exactly what was printed on Mullins's T-shirt. (Spoiler alert: At the end of the movie, Montoya does find the fiend, and he says his line over and over. It's awesome.)

Mullins explained to Stuff that a flight attendant had approached him before takeoff and asked that he put on a different shirt due to some concerned passengers. Mullins told Stuff:

I thought it was all a bit silly. The person next to me was laughing, because they knew the movie.

The flight attended apparently told Mullins she would attempt to find him another shirt, but never did, so the T-shirt stayed on. "I wouldn't be surprised if they had someone watching me the whole time," Mullins said. "The whole experience was a bit over the top, but also a bit comical."

Here's the scene that started it all:
