The man takes his wife to the stock show. They start heading
down the alley that had the bulls. They come up to the first
bull and his sign stated: "This bull mated 50 times last
year." The wife turns to her husband and says, "He mated 50
times in a year, you could learn from him."
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 can learn from this one, also."
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 man turns to his wife and says, "Go up and inquire if it
was 365 times with the same cow."
