John Kerry is in London today to hold talks following the UK’s decision to leave the European Union.
And he smashed his head on the door of No.10 Downing street.
The US Secretary of State is due to hold talks with Theresa May. He will also take part in a press conference with new foreign secretary Boris Johnson later today - possibly while holding a bag of frozen peas to his temple.
A spokesperson for the prime minister said she was “proud” of the Downing Street doorkeepers who had done an “excellent job” given they had to open the famous door “a lot” in recent weeks.
Perhaps Kerry should have hummed a little tune to warn the doorkeeper he was coming.
