'The Princess Bride' is known for many famous lines, perhaps the most famous of which is the classic, "Hello. My name is Inigo Montoya. You killed my father. Prepare to die." It's quoted and repeated and even reprinted on t-shirts. But you might not want to wear your Inigo Montoya shirt on your next airplane flight lest you wind up like poor Wynand Mullins whose 'Princess Bride' t-shirt was deemed a security risk. Inconceivable!
