The three-legged chicken

A man was driving along the motorway when he noticed a chicken running alongside his car. He was amazed to see the chicken keeping up with him, as he was doing 60 mph. He accelerated to 70, and the chicken stayed right next to him. He sped up to 75 mph, but the chicken overtook him.

Then the man noticed that the chicken had three legs. So he followed the chicken, speeding all the way, and ended up at a farm. He got out of his car and saw that all the chickens on the farm had three legs.

When he spotted the farmer he asked him, "Where did you get these chickens?"

The farmer replied "Well, everybody likes chicken legs, so I bred a three-legged bird. I'm going to be a millionaire."

The man was impressed and asked him how they tasted. The farmer said, "Don't know, I haven't caught one yet."
