Always make sure to wrap tin foil (aka aluminum foil in the United States, or aluminium foil in the civilised world) around your head. This prevents the CIA from applying their telepathy and reading your thoughts.

I once sat down without tin foil wrapped around my head, and yossarian (who is an employee of the CIA, as this anecdote clearly shows) stole my Chatterbox line before I even had a chance to type it.

Let's see you do that with all the tin foil on my head, sucker!
