A female TV reporter arranged for an interview with a farmer, seeking the
main cause of Mad Cow disease.

The Lady: Good evening, sir. I am here to collect information on the
possible source of Mad Cow Disease. Can you offer any reason for this
disease?

The Farmer stared at the reporter and said: Do you know that a bull
mounts a cow only once a year?

The lady reporter (obviously embarrassed): Well, sir, that's a new piece
of information, but what's the relation between this phenomenon and Mad
Cow disease?

The Farmer: And, madam, do you know that we milk a cow twice a day?

The reporter: Sir, this is really valuable information, but what about
getting to the point?

The Farmer: I am getting to the point, madam. Just imagine, if I was
playing with your tits twice a day and only screwing you once a year,
wouldn't you get mad?
