Nice plums.

First go to great trouble to pick as many plums as you can.
Use one of those long-handled grabbers so you can reach the higher branches.
Put the plums in a dish in the fridge.
Leave them in there for a few weeks.
When they are nice and mouldy take them out of the fridge ....
And THROW them away!

Well not this time!
