"Hello there... No, no actually. Not Boston this time... I need this call transferred to Washington D.C."
The "European Phonebook" is a meme/trope that states any one person can use a European to recall the phone number(s) of any person in the world to call. This makes Europeans notable as not only being colonializing bastards, but mobile biological telephone and address books.
"European Phonebook" is commonly invoked when a world leader or significant figure calls for someone else important to be contacted across the world.
