Okay, by popular demand, one last go.

A friend was telling me about one of his horses. It seems that one day, somebody fed her a cracker, and she developed a taste for baked goods.

"That's all she'll eat now!" he said. "Sourdough, baguettes, rye, whole wheat. I can't understand it!"

I asked, "Is it one of your racing horses?"

"Yes," he replied.

"Well, there's your problem right there. She's a thorough-bread."
