In a remote part of the country, a strapping young farmhand was sent to the station to pick up the new school teacher who turned out to be an attractive young woman.
On the way back to the farm she noticed a stallion mounting a mare. “How do they know when to do that?” she enquired.
The young man explained that it was a sense of smell.
In the very next paddock a bull was enjoying himself on a cow.
“Again, it is a sense of smell,” explained the country boy. “Just like that ram and ewe over there.”
They got to the farmhouse, where he unloaded her luggage and turned to go. “See you later,” he said cheerily.
“Thanks,” she replied. “And do come over when your cold gets better.”
