The BBC's hit comedy Gavin & Stacey was back with its winning formula of gooey romance, slapstick angst and recurring logistical challenge of getting a vast ensemble of Essex and Welsh people into the same room without it seeming odd. Perhaps that's its genius. This week they solved it with a christening party, adding yet more characters. Here was Nessa's dad and Smithy's mother (Pam Ferris, looking like she'd slept in a skip), and Ewan Kennedy was cracking as the new baby, Neil - strapped facing outwards on Nessa's back. "That's so I can smoke," she drawled.

The Welsh steal this show, led by Ruth Jones as Nessa - gnomic, brusque, experienced - alongside her spiritual opposite, Bryn (Rob Brydon), garrulous, sentimental and unworldly. I don't know about the Billericay element. Alison Steadman is a bit of a pantomime grotesque as Gavin's mum, and Smithy's Byronic laments for Gav - now installed in his new job in Cardiff - are fast losing their charm. I'm all in favour of a man expressing his feelings but if Smithy were my best mate I think I'd have to move farther than Wales.
