Dad Martin (Paul Ritter) is a bit stressed, his old friend Tony is coming to dinner. He reconnected via the internet and got the wrong Tony, it’s the one from the old days he didn’t like. “Don’t blame me, blame my brain,” he says when the family hides from Tony in the kitchen. All is set for a cracking first episode in the fourth series.

And it helps that Tony is played by Jason Watkins - you’ll know his face from loads of stuff – who is irritating from the first of many painfully punny dad jokes he comes out with. “This is a shitting nightmare,” says Martin, while Tony, who blinks like a tortoise, is upstairs in the toilet.

Oh, and of course Jim (Mark Heap) is at the front door too. “Is your mum in? It is an emergency situation.” His dog has eaten the hob knobs and his cooker has broken, meaning that he wants mum Jackie (Tamsin Greig) to cook his fish.  

There is nothing particularly groundbreaking here. Just a lovely, well-observed, faintly farcical fast-moving storyline as one minor white lie – they claim Jackie’s mother has died so that they can cancel dinner and turf Tony out – sends events spiralling out of control. 

Sons Adam (Simon Bird) and Jonny (Tom Rosenthal) take something of a back seat this week, but not before Jonny has tipped some pepper onto Adam’s plate when he is not looking. In other words it’s business as usual. As Tony might say, my condiments to writer Robert Popper.
