Nod has a gardener who visits about twice a year. The gardener has heard about Nod's cancer treatment.
He comes round to do some gardening.

Gardener (laying hand on Nod's arm): Dear Lord, we love Nod and ask that you cast these demins from his bowels and send your love to your child Nod....etc. for about 3 minutes
Nod: Thanks, but I have to go
Gardener: But I haven't finished!!
