"Well, doc, 25 years ago ..."

"Never mind the past. Tell me how you broke your leg this morning."

"Like I was saying... 25 years ago, when I first started working on
the farm, I was a strapping young fellow, that night, right after I'd
gone to bed, the farmer's beautiful daughter came into my room. She
asked me if there was anything I wanted.

I said, "No, everything is fine."

"Are you sure?" she asked.

"I'm sure," I said.

"Isn't there anything I can do for you?" she wanted to know.
"I reckon not," I replied.

"Excuse me," said the doctor, "What does this story have to do
 with your leg?"

"Well, this morning," the farmhand explained, "when it dawned
on me what she meant, I fell off the roof!"
