"Good evening sir", she began. "I'm here to collect information on the possible source of Mad Cow Disease. Can you offer any reason for this disease?"

"Did you know that a bull only mounts a cow once a year?" the farmer asked.

Obviously embarrassed, the reporter said, "Well sir, that's a new piece of information, but what's the relation between this phenomenon and Mad Cow Disease?"

"And," continued the farmer, "do you know that we milk a cow twice a day?"

"Sir, this is really a valuable information," said the lady reporter, "but what about getting to the point?"

"I am getting to the point, young lady," the farmer insisted. "Just imagine, if I was playing with your tits twice a day and only screwing you once a year, wouldn't you get mad?"
