Tom Jones Fever A guy walks into his doctor's office one afternoon and says ""Doc, I can't sleep. When I lay on my right side, I hear the song 'Delilah'. When I lay on my left side, I hear the song 'The Green Green Grass of Home', what's wrong with me?"" The doctor pauses for a moment before saying ""Oh dear lord...it sounds like a bad case of Tom Jones Fever"" The man replies ""Tom Jones Fever? I've never heard of that. Is it common?"" The doctor says ""Well, it's not unusual.""
