Public Image (song) Puns

A while ago I was sat down to dinner with my family, a delicious meal as it always is, ta very much Mum. Throughout dinner and the usual post-dinner chatter Dad had been muttering "My my myyyy Delilah..." to himself. Usually you can ignore a bit of a quiet singsong someone outside of a conversation is having to themselves but every 10-15 minutes he'd go "My my myyyy Delilah...". A good 2 hours after starting our dinner my sister feels the need to ask "Dad, why do you keep singing my my my delilah? Was there a song on the radio or something?". Dad gives a confused little look and goes "Hmmm? What? Oh dear oh dear oh dear... It's actually a medical problem. I went to the doctor about it recently" then raises his head trying to conceal that grin that we all know and dread. "He said I had Tom Jones Syndrome. I asked if it was common. He just shrugged and said it's not unusual". I gave him two thumbs up and a look of respect, most of the table gave a horrified groan. 2 Hours! the dedication on that man!
