I need some good cow jokes?

A city man was tooling down a country road when his car sputtered to a complete stop near a field filled with cows. The driver, getting out to see what was the matter, noticed one of the cows looking at him. "I believe it's your radiator," said the cow. The man nearly jumped right out of his city slicker britches! He ran to the nearest farmhouse and knocked on the door. "A cow just gave me advice about my car!" he shouted, waving his arms franticly back toward the field. The farmer nonchalantly leaned out beyond the door frame to glance down the field. "The cow with two big black spots on it?" the farmer asked slowly. "Yes! Yes! That's the one!" the excited man replied. "Oh. Well, that's Ethel," the farmer said, turning back to the man. "Don't pay any attention to her. She doesn't know a thing about cars."
