A man takes his wife to a livestock show. They enter the tent that
houses all the bulls. The sign on the first bulls 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 70
times last year." The wife turns to her husband and says, "This one
mated 70 times last year, that's almost 6 times a month. You could
learn a thing or two from this one!"
They carry on to the last bull and his sign said: "This bull mated 365
times last year." The wife's mouth gapes open and says, "WOW! he mated
365 times last year, that's ONCE A DAY! You could really learn from
this one."
The fed up man turns to his wife and says, "Go up and enquire if it
was 365 times with the same cow."
