This guy goes to see his doctor. "Doc," he says, "I've got a problem, every minute of every day I've got that old song, Delilah, running through my head. I catch myself humming it and sometimes singing it in public places. My wife says I even sing it in my sleep, it's driving her nuts. What is the matter with me?"
The doctor replies, "Sounds like Tom Jones Syndrome to me."
"Is it a rare disorder?" the guy asks.
The doctor answers, "It's not unusual.."
