Language Barrier Misunderstanding

A female BBC reporter was conducting an interview with a farmer about Mad Cow Disease.

"Sir, do you have any idea what might be the cause of this strange disease?"

"Sure. U c, we rear our cows on zero grazing. Thus their movements r restricted to zero. Furthermore, bulls only screw the cows once a year?"

"Umm, sir, that is a new piece of information, but what's the relationship between this and Mad Cows?"

"Well, we milk the cows twice a day n in some, thrice daily"

"That's interesting, but, what's the point sir?"

"Lady, yaonekana hushikanishi mawaya. The point is this, if I'm playing with your tits twice a day, but only screwing you once a year, wouldn't you go mad too?"
