Cameron's musical exit: "Winnie the Pooh" or "West Wing?"

David Cameron was caught humming a little tune to himself shortly after he announced Theresa May would become the next UK Prime Minister.

Curious minds wanted to know WHAT Cameron was humming. Candidates included "Yes Minister", "The West Wing", "Shostakovich's 5th," "Winnie the Pooh," "Schools out for Summer", "The Final Countdown", and "The Great Escape".

Personally, I would opt to name it "Happy Exit".
