One evening, as Uncle John and his wife 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 fucking 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'- not some filth you picked up in the City," he says.
A few days later, little Johnny comes 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 fucking the horse!"
