While campaigning for the Democratic presidential nomination one day, JFK visited a mine in West Virginia.

"Is it true you're the son of one of our wealthiest men?" one of the miners asked.

Yes, Kennedy reluctantly replied.

"Is it true that you've never wanted for anything and had everything you wanted?"

"I guess so."

"Is it true you've never done a day's work with your hands all your life?"

Kennedy nodded.

"Well, let me tell you this," the miner declared. "You haven't missed a thing!"
