Mr. Bean S02E03 - Royal Bean

After a faulty toaster accidentally breaks Mr. Bean's favorite mug with Queen Elizabeth II's face on it, he drives to town to buy a new one. He then finds a lorry carrying mugs with the Queen's face on it, causing him to chase the lorry to Buckingham Palace. Once there, the Queen's corgi steals Teddy, resulting in Bean giving chase. Eventually, Bean manages to bring the missing dog back to Elizabeth and is rewarded with a new mug, much to his gratitude.
