So this guy goes to the doctor and says
“Doc, I don’t know what’s wrong with me. I can’t stop singing ‘What’s new pussycat’ and other songs by Tom Jones”
The doctor listens…strokes his chin…and says “Actually, I have seen this before and I know what it is”
Patient: “What’s happening?”
Doctor: “It’s called ‘Tom Jones syndrome'”
Patient: “What? I’ve never heard of this before? Should I be worried? Is it rare?”
Doctor: “It’s not unusual”
