Friends fans have spotted a huge error at Monica Geller and Chandler Bing’s wedding, years after the nuptials originally aired.

In the run-up to the couple’s big day, Monica found herself in a bit of a pickle with rival bride Megan all over her dream dress.

After trying on her white gown at an expensive high-end store, Monica kindly advised fellow shopper Megan that she could also buy one for much cheaper at discount store Kleinman’s.

But when Monica, Phoebe and Rachel headed to the store, they had to battle it out with Megan as she had her eyes on the same – and only – dress that Monica wanted, too.

After they managed to rugby tackle her to the floor and run home with the dress, Megan booked the Swing Kings – the band Chandler so badly wanted for their wedding – in retaliation, saying Monica couldn’t have both. Monica ended up giving away the dress to Megan so they could book the Swing Kings.

But if you’re wondering where the inconsistency is, then it turns out that the couple didn’t even book that band after all that drama. I KNOW!

Watching a rerun of the beloved sitcom, one fan took to Twitter to point out that the band’s amps and drums at the wedding read ‘Jungle Swing’ as the newlyweds took to the floor for their first dance (or in Chandler’s case, slip around) as a married couple.

And according to some fans, Jungle Swing actually played at Barry and Mindy’s wedding way back in season two. Who knew?!
