Just hours after UK Prime Minister Boris Johnson announced his resignation, a Burger King truck drove past Parliament and 10 Downing Street with text mocking the departing leader, in a campaign facilitated by BBH.

Text on the side of the truck read: “Turns out there is such a thing as too many Whoppers.” A Whopper is the name of Burger King’s flagship burger, as well as a British slang term for a lie.

The text and Burger King logo are shaped like the number “10,” while the black backdrop appears to mimic the iconic door of 10 Downing Street, where Johnson lives.

Johnson announced on Thursday that he was standing down as prime minister but would stay in post until a successor is named. The announcement came after dozens of ministers resigned over the course of the week, including chancellor Rishi Sunak, following revelations that Johnson had known about sexual misconduct allegations made against Chris Pincher, a senior member of Johnson’s staff before his appointment as chief whip in February.
