There are certain things you just don't mess with - and one of them is the proper way to make a cup of tea.
Fully aware of how touchy a subject this is for the British, the US Embassy in London masterfully trolled the UK by posting a video celebrating International Tea Day, showing a man enjoying a cup of tea that had been heated up in the microwave.
The video has, of course, gone viral on social media, with people dubbing it an outright "declaration of war".
