George and Lynne are out and about in the rain. Lynne tells George that a TV weatherman named Wes and TV weathergirl named Wendy have just had a child. George asks if it's a boy or a girl. Lynne says it is a son.
It is raining heavily and both George and Lynne are prepared, wearing overcoats and carrying an umbrella. The weather people have got it spot on of course.
We do not know if Wes and Wendy are married or whether this is the culmination of a brief romance. The story probably would have made the papers and that's where Lynne has picked up on the story. They do not work for a TV channel as Lynne hasn't mentioned it, which means that perhaps they were both sacked for their dalliances.
Lynne says they have had a son, but points to the sun. George will have to be on his toes to get Lynne's joke. She is lucky that the sun is out otherwise the end of the conversation would have been quite boring. Actually, it would have the same as it is, quite boring.
