Tourists touching down at Heathrow Airport are being given a lesson in British etiquette by a famous face.
Before they are allowed to step off the plane, visitors are treated to a hilarious video fronted by British funnyman Stephen Fry.
Using his oh-so-dry-English wit, Fry explains the rules of "how to be British"; this includes joining in the chorus of cheers when glasses are accidently smashed in a pub and mastering the art of the "agreement rule" when a stranger comments on the weather.
Fry explains the "after you" rule.
Fry collaborated on the three minute video with Graham Linehan - who won a scriptwriting Bafta for The IT Crowd.
"We know from our passengers that it's important to them to feel they have arrived in the UK from the moment they disembark from the plane," Heathrow chief executive, John Holland-Kaye, said.
"And what better way to do that than with a fun film from one of the country's most beloved comedians."
