This one is from Will & Guy.
A young couple invited their aged Vicar for Sunday lunch. While they were in the kitchen preparing the meal, the minister asked their son what they were having.
“Goat,” the little boy replied.
“Goat?” replied the startled reverend. “Are you sure about that?”
“Yep,” said the youngster. “I definitely heard Dad say to Mum, ‘We might as well have the old goat for dinner today as any other day’.”
