One evening, as Uncle John and Aunt Millie are entertaining guests with cocktails, they are interrupted by an out-of breath little Johnny who shouts out, "Uncle John! Come quick! The bull is f---ing the cow!"

Uncle John, highly embarrassed, takes young little Johnny aside and explains that a certain decorum is required.

"You should have said, 'The bull is surprising the cow'- that is much more polite than using a swear word," he says.

A few days later, little Johnny comes over again as his uncle and aunt are entertaining.

"Uncle John! The bull is surprising the cows!"

The adults share a knowing grin.

Uncle John says, "Thank you little Johnny, but surely you meant to say the cow, not COWS. A bull cannot 'surprise' more than one cow at a time, you know."

"Yes he can!" replies his obstinate nephew, "He's f---ing the horse!"
