This Princess Bride Using That Word T-Shirt features a picture of Inigo Montoya and his comment to Vizzini when the man in black does not fall to his death. "You keep using that word. I do not think it means what you think it means." The word "inconceivable" became a catch phrase for the Sicilian criminal mastermind, Vizzini. Inigo remains one of the most popular characters from the classic 1987 movie on his quest for justice.
