The prime minister stepped down today, as promised. Though Cameron's legacy is...complicated, his final departure was perfection. Cameron posted the photo below of himself and "Chief Mouser to the Cabinet Office" Larry on Twitter. (Their relationship, considering Cameron is reportedly a dog person, has always been suspicious.) Side note: The Downing Street cat must also say goodbye to the Cameron family; he will be staying on at Number 10.

The almost-ex-premier even showed the MPs that photo of him with Larry during his final PMQs appearance. Then, Cameron ended a truly moving speech about the power of politics and public service with a final line that may, perhaps, end up acting as his epitaph: "I was the future once."

See the last minute of his speech below. Remember: No matter what the circumstances, It's always good to go out with a laugh.
