car problems

A man's car stalled on a country raod one morning. When the man got out to fix it, a cow came along and stopped beside him.
"Your trouble is probably in the carburetor," said the cow.
Startled, the man jumped back and ran down the road until he met a farmer.
The amazed man told the farmer his story.
"Was it a large red cow with a brown spot over the right eye?" asked the farmer.
"Yes, yes," the man replied.
"Oh! I wouldn't listen to Bessie," said the farmer. "She doesn't know a thing about cars."
