This is a sketch I am too lazy to write, so I am throwing it open for others to chip in.
In the spirit of G Wily a weather forecaster is giving the prospects for different parts of the country, only in this case the weather predicted rhymes with the places mentioned.
The rhymes can be either used directly, e.g.
You will need overcoats in Saltcoats
Or inferred, e.g.
In Bude you will be able to get a good all over tan
In Missenden it will be raining really quite hard
Have fun with it, and should we get enough I will have ago at assembling the best of them into a working sketch.
