SAN JUAN (The Borowitz Report)—Calling the move an “urgent response to recent unfortunate events,” Puerto Rico has issued a sweeping travel ban on malignant narcissists, effective immediately.

Starting on Wednesday, Customs and Border Protection officials at Puerto Rico’s ports of entry will be equipped with the Diagnostic and Statistical Manual of Mental Disorders (DSM–V) issued by the American Psychiatric Association, and will be instructed to look for symptoms of malignant narcissism in those attempting to enter.

“If port officials encounter a visitor who has a pompous and arrogant demeanor, needs the constant admiration of others, and is unwilling to empathize with others’ feelings, wishes, or needs, that visitor will be denied entry,” a Puerto Rican government statement read.

Puerto Rico took the forceful action after an incident on Tuesday, in which a man with narcissistic-personality disorder gained entry to the island and inexplicably hurled projectiles at unwitting Puerto Ricans.

“We had to do something,” one government official said. “Enough is enough.”

Puerto Rico’s ban on malignant narcissists drew widespread praise from people around the world, with many Americans calling for a similar ban in the mainland United States.
