"Hanging his balls on the Christmas Tree"

I'm sure I heard this as an out-take from the Waltons, said by John Boy.
Yesterday I finished off the Cherry Tree by hanging the large baubles on the branches. Quite effective when the lights are on.
I've timed the outside lights to come on at 16:00 and go off at 00:00. Some of them are controlled by 'Smart Life' app and others by mechanical timers plugged into the mains, coming from the garage and another from the outside socket on the wall in the back garden.
