Despite this, both have said they would highly recommend going as Nessa and Smithy for Halloween, and said that one of the best parts was having an excuse to go to KFC for "props".

There are a small number of TV shows that have done such an epic job in creating memorable characters and catchphrases that they actually end up becoming common vernacular. Gavin and Stacey is one such show. I mean, am I the only one who takes every opportunity to exclaim, “Oh my christ!”? I think not. I mean, we all see some of our own families and friends in the Wests and the Shipmans, right? And although Nessa may not be a title character, there’s no denying she had some of the best lines in the whole show. Ruth Jones’ fictional anti-heroine is outrageous and straight to the point. I won’t lie to you, we could do with Nessa’s unique brand of savagery right now. According to the duo, Lea shotgunned Nessa because her mum already owned the boots. They pretty much owned most of their outfits already, apart from the Smithy wig, shirt and Nessa's Welsh hat. The Nessa wig was recycled from their friend who went as Mia Wallace the year before and was given a Nessa worthy hair cut. The girls have also revealed dressing as such iconic characters had its benefits as they got their five minutes of fame whilst out and about in The Diff. Gwenllian has said: "We got tons of people saying how much they liked our costumes and asked to take pictures. A couple of people were even sending pics to their family group chats which was pretty funny." With three seasons and a couple of explosive Christmas specials under its belt, the show is one you can revisit again and again. Fans proved the love is still strong when, after a nine year break, 18.5 million people tuned in to the Christmas special in 2019. Some speculated whether it was a sign that Ruth Jones and James Corden would be joining forces once again to give fans the season four they’ve been dying to see. However, as Corden is settled stateside and Jones has resumed her post in Cardiff as a true Welsh icon, it isn’t looking likely.
