A man takes his wife to the stock show. They head 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 ask if it
 was 365 times with the same cow."
