A man takes his wife to the live stock show.
They start heading down the alley that houses all the bulls.
The sign on the first bull`s stall states: "This bull mated 50 times last year."
The wife turns to her husband and says, "He mated 50 times in a year, isn`t that nice!"

They proceed to the next bull and his sign stated:
"This bull mated 65 times last year."
The wife turns to her husband and says, "This one mated 65 times last year. That is over 5 times a month. You could learn from this one!"

They proceeded to the last bull and his sign said:
"This bull mated 365 times last year."
The wife`s mouth drops open and says, "WOW! He mated 365 times last year. That is ONCE A DAY!!! You could really learn from this one."
The fed up man turns to his wife and says, "Go up and inquire if it was the same old cow every day."
