Father, Dear Father - Season 3 (1970)

Mr. Schulz, an American movie mogul, wants to make a film out of one of Patrick's books. However, he is a very religious man who does not hold with divorce so that, when he and his wife come to Patrick's for dinner, the host has to supply a Mrs Glover. Barbara initially refuses but a friend of Georgie, Jo, agrees to the masquerade. All is going well until Barbara, who has had second thoughts, turns up,claiming to be Patrick's current wife - and, trying to be helpful, Nanny also claims to be married to Patrick.

Annoyed that his dog, H.G. has chewed up the manuscript of his latest book, Patrick gives him away to Ian, his publisher, earning the disapproval of Nanny and his daughters, who are shocked that he was so callous. When Ian's house is burgled, the police work out that it was the dog who let the burglars in so Ian returns him to Patrick, though the girls and Nanny have also lined up other dogs for him.

When Patrick's mother reminds him that Karen never had a proper christening, Patrick - and Barbara - decide to rectify this and go to see their local vicar. The vicar is expecting a couple who are about to get married and assumes this is Patrick and Barbara. In their innocence they answer all his questions, unaware that they are at cross purposes. The big day arrives and the vicar is about to marry Patrick and Barbara when Bill, long jealous that Barbara wants her ex-husband back, clouts Patrick. Ultimately the misunderstanding is resolved and the christening proceeds.
