The look on Joey's face here is priceless
She'd just been laughing about how he made smoothies very dense with oats so 'they' (Niomi) had limited the oats to 2 tablespoons. She then says she's turning the camera off while they figure out the ingredients. When she turns it back on there's a moment you can really tell he's annoyed. At 1:50 she says 'This is really flustering you!' and he says 'I've just woken up and it's like 'make a smoothie, you're the smoothie guy!''
Then the way she goes on at him as he's making it, as though she knows best, laughing, being patronising - I don't know how he had the patience to put up with it! Although I do now wonder how many rows they had off camera.
