Seulement quelques exemples :

The Avengers. "Chapeau melon et bottes de cuir" in France.

British sense of humour.

Some of my favourite beers.

"Filer à l'anglaise" (Never understood why you say: to take the French leave)

Agatha Christie et mes séries policières préférées…(Couldn't find the words in English)

The Beatles and pop music innovations.

English country dances and my favourite traditional music after Scottish one.

Keeping France in the victory camp after WWII. Thank you Winston Churchill.
(By the way, a thought for all the Tommies who gave their lives for our freedom during WWI and WWII). Thank you Winston Churchill.

I was about to mention Catherine Zeta-Jones but she's Welsh, isn't she?

What is wrong now :

Quite a lot naval defeats! Thanks you Lord Nelson!

Guillotine concept.

The destruction of Le Havre my hometown in september1944 (about 2000 civilians killed).
The slaughter of French sailors at Mers-el –Kebir. My father-in-law was on board the Strasbourg.

What French Canadians call "le grand derangement".

Hooligans (sorry, we have ours, just see a football match between Paris and Marseilles).

Driving on the wrong side of the road (well I'm kidding).

Killed Joan of Arc and transported Napoleon. In fact, I fear people feel more interested by the Corsican ogre in England than in France.

Télétubbies (the French name?)

Mrs Thatcher.

Pourquoi autant d'endroits en Angleterre portent-ils des noms de défaites : Trafalgar Square, Waterloo station… ? (It's only a joke)
