Do nursery rhymes have secret interior meanings?

Good question ......

I have always wondered about "rub a dub dub three men in a tub" "Rock a bye baby" and "Humpty Dumpty."

Yes they do .... I can't say anything more cos hickory dickory dock .... I'm being so good right now :) i have a filter and I think we should all apriciate that now :) I .... Am ...AWESOME!!

Some may have.

There's a modern tendency to add meaning where none existed, however some of them undoubtedly had a meaning,

But here's a story for Jaimie in view of her answer.

There was a barman called Dick whose favourite customer was a doctor always rushed in after his day at the hospital and had one walnut daiquiri (that's a daiquiri with a walnut in it) to settle his nerves after a day at the hospital.

One afternoon, as the time approached, Dick realised that he had no walnuts but, behind the bar, he found some hickory nuts. As the doctor approached he slipped one into his glass, poured in the booze, and hoped for the best.

The doctor took a couple of tentative sips and asked, "Is this a walnut daiquiri, Dick?"

"No. It's a hickory daiquiri, Doc."
