Cow mechanic

A man was driving down a country road in the middle of dairy farm country when his car stalled inexplicably. He got out and raised the hood to see if he could find out what had happened.
A black and white cow slowly lumbered from the field she had been grazing in over to the car and stuck her head under the hood beside the man. After a moment the cow looked at the man and said, “Looks like a bad carburetor to me.” Then she walked back into the field and began grazing again.
Amazed, the man walked back to the farmhouse he had just passed, where he met a farmer. “Hey, mister, is that your cow in the field?” he asked.
The farmer replied, “The black and white one? Yep, that’s old Bessie.”
The man then said, “Well my car’s broken down, and she just said, ‘Looks like a bad carbuerator to me.'”
The farmer shook his head and said, “Don’t mind old Bessie, son. She doesn’t know a thing about cars.”
