"So, how did it happen?" the doctor asked the middle-aged farmhand as he set the man's broken leg.
"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, and one spring 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."
