You all may have read about the Iranian plot to kill the Saudi Ambassador to the U.S. using a Mexican Drug Cartel assassin, who may or may not have been a CIA operative.

CIA Assassin: So an Iranian intelligence officer and an assassin walk into a Mexican bar looking to assassinate the Suadi Ambassador.
FBI Agent: What’s the punch line?
CIA Assassin: I’m the f***ing punchline!
