Watching classics movies has been a mainstay of the Christmas period for many, with My Fair Lady remaining a much-loved favourite.
But fans of the musical had their minds blown by a tweet about a hidden phonetic pun in the film’s title.
A post on social media by comedian Mark Lamarr went viral 'reminding' people of the little-known piece of information.
His tweet claimed: “Reminder that it’s called My Fair Lady as that’s how Eliza would pronounce Mayfair.
“The greatest and most understated phonetic pun in any movie title.”
Mark added: “It comes as quite the revelation when one notices it, but it’s been hiding in plain sight all along.”
The tweet has been seen by more than 408,000 people, and garnered more than 2,700 likes and hundreds of retweets.
Twitters users were amazed to discover the pun despite the movie, starring Audrey Hepburn and Rex Harrison, being around for nearly 60 years.
One person said: “Whaaaaaat!! *head swivels* how did I miss that!”
Another user wrote: “One of my mum’s favourite films and now I’m wondering if she realises the pun. I’ll be honest, I’ve never seen the film so I thought it was just describing the lead female.”
A third posted: “I’ve seen this film a million times (musical favourite) and that fact never twigged with me! Wow!”
Another user added: “What??? As in ‘Mayfair’ Lady with a cockney accent??? I’m not ready for this.”
The tweet was doubted by a few people though, querying whether the title was actually taken from the song London Bridge is Falling Down.
Mark responded: “That being the nature of a pun. The movie is about a phonetics professor, not a bridge falling down.”
