Stan samples the home-brewed beer which he has just made. It is very, very strong indeed, so much so that when he goes to work he is already tipsy and Blakey breathalyses him. Thanks to Jack's little ploy the result is negative and Blakey assumes Stan is ill, sending him home. Here he finds that the family have well and truly been partaking of the home-brew and Arthur and Olive are getting very amorous with each other.
