It’s been five whole years since the 2019 Christmas special and we have been impatiently waiting to find out whether Smithy accepted Nessa’s proposal or not.

But when it was announced by writers and actors James Corden (Smithy) and Ruth Jones (Nessa) that last night’s Gavin and Stacey episode was planned to go ahead and was also the final ever instalment, we believed that the couple would obviously be walking down the aisle within the first few minutes.

Well, we were wrong.

We had Smithy and Nessa finally getting together, Neil the baby (Oscar Hartland) singing at his dad’s first wedding as well as the revelation that Gwen (Melanie Walters) and Dave Coaches (Steffan Rhodri) had been getting it on for six months in secret.

So much good stuff.

But let’s take it back to the stag do.

As more than 12 million people watched Smithy’s belated stag, which he was incredibly late to, eagled-eyed fans noticed a hilarious detail that most people completely missed.

It was when the boys turned up to celebrate with him that they all revealed that they were wearing West Ham footy shirts, with Bryn (Robert Brydon) even donning the shorts and socks too.

However, what you probably didn’t see was that among them all, one person refused to wear the signature badge as part of his shirt.

It was none other than Gavin.

As a Tottenham Hotspur fan, there was no way that Gav was going to betray his team for anyone, not even Smithy.

So, as you look around the group of men, you’ll see that he’s the only person who didn’t wear it.

Fans have since taken to TikTok to talk about the detail (which I’m ashamed to say that I also missed), and commented on Gavin and Stacey Clips channel, who pointed out the badge.

One person said: “I didn’t even spot that.”

Another praised: “It’s the details like this that make the show.”

But there is so much more that you probably didn’t know about the show.

A Q and A with the cast brought to light numerous behind-the-scenes moments which made the episode so much better.

Apparently, two extras went off-script during the wedding scene with Smithy and Sonia (Laura Aikman), which was seen when they stood up to object to the couple’s nuptials, even though they were seated on Sonia’s side.

For the scene, there were about ‘40 to 50 extras’ in the room as guests while Neil the Baby sang his cover of ‘Blackbird’.

Larry Lamb (Mick) explained that they all ‘sort of knew the story’ because they were all Gavin and Stacey fans, but nobody expected them to take charge of the scene.

“And the looks on their faces – the shock – it was just absolutely brilliant,” Lamb said.

When the officiant (Anna Maxwell Martin) asked if anyone else felt the same as Gavin and didn’t want the pair to get married, members of the Essex and Welsh families slowly began to stand, as did the extras.

“When Anna said, ‘Please stand’, there’s two ladies at the back on Stacey’s side who stood up! We didn’t tell them to,” Corden said.
