West Ham United have become the first Premier League club to appear in The Simpsons — there is just one slight problem — the show got their colours wrong.
A flag celebrating the Hammers appears in the latest episode of the long-running cartoon but it is in green and not the club's famous claret and blue.
The flag is shown in the bedroom of a character called T-Rex — a new character who moves in next door to the Simpsons.
West Ham United didn't seem bothered by the mistake though as they proudly reported the news on their official Twitter account.
"West Ham United were delighted to be featured in The Simpsons episode 'The Day The Earth Stood Cool' on Sunday!" the club said in the statement.
The Simpsons is now in its 24th season and has broadcast over 500 episodes.
So far the Brazilian Ronaldo is only footballer to have been given a guest spot as himself on the show when he appeared in the season 18th show 'Marge Gamer.'
A character resembling David Beckham helped cause a British invasion in another episode but Golden Balls himself was deemed 'not famous enough' for a full guest star spot in 2010.
