A group of retired farmers were travelling by tour bus through Devon.
They stopped for a tour at a dairy, and a young guide led them through the process of cheese making, explaining that at this particular dairy goat's milk was used.
She then showed the group lush, green field where many goats were grazing.
'These' she explained, 'Are the older goats. We put them out to pasture when they can no longer produce'milk.
She then asked, 'What do you do with your old goats?'
A spry old gentleman answered, 'They send us on bus tours!'
