Bull Or Not?

A man took his wife to the County Show and one of the exhibits is that of breeding bulls.

They went up to the first pen and there was a sign that said "This bull mated 50 times last year"

The wife poked her husband in the ribs and said, "He mated 50 times last year"

They walked a little further and saw another pen with a sign that said "This bull mated 120 times last year".

The wife hit her husband and said, "That`s more than twice a week! You could learn a lot from him".

They walked further and a third pen had a bull with a sign saying, "This bull mated 365 times last year".

The wife got really excited and said,"That`s once a day you could REALLY learn something from this one".

The husband looked at her and said, "Go up and ask him if it was all with the same cow".
